BREAKING: JAMB Issue Important Update for 2025 Mop-Up Examination (Press Statement)

 


 REPRINT OF EXAMINATION MESSAGES IN CIRCULATION NOT FROM JAMB

We wish to draw the public’s attention to the misleading messages circulating via a spoofed version of our 66019 shortcode. These messages instruct candidates—some of whom have already sat the resit examination and received their results—to reprint examination slips for another examination.

We hereby categorically state that these messages are not from JAMB. There are currently no scheduled examinations, and candidates who have successfully completed the resit examination and received their results need not be concerned. Such messages are fraudulent and intended to sow confusion.

The only examination that JAMB is planning to conduct, which has yet to be scheduled, is the foreign examination held in nine countries across Europe, the Middle East, and certain African nations.

 Additionally, there will be a mop-up examination for candidates who missed the main and resit examinations and have been granted waivers only for 2025 to participate in the usual mop-up for those who experienced biometric failures.

We urge the public to disregard these deceptive messages. Those qualified for the mop-up examination, as specified, will be duly notified once preparations are finalised.

How Air Conditioners Really Work – Understanding the 5 Crucial Components:


An air conditioning (AC) system is designed to control temperature, humidity, and air quality. It achieves this through a cycle of heat absorption and release using five main components: the compressor, condenser, thermal expansion valve, evaporator, and fan.


1. Compressor: 

Often called the heart of the AC system, the compressor compresses the low-pressure refrigerant gas into a high-pressure, high-temperature gas. This is essential to circulate the refrigerant through the system.


2. Condenser: 

Located outside the building, the condenser receives the high-pressure gas from the compressor. As air flows over the condenser coils, the refrigerant loses heat and condenses into a high-pressure liquid. This process releases the absorbed heat into the outside air.


3. Thermal Expansion Valve (TXV): 

This small but critical component regulates the amount of refrigerant entering the evaporator. As the high-pressure liquid refrigerant passes through the valve, it expands and cools rapidly, becoming a low-pressure, low-temperature mixture.


4. Evaporator: 

Found inside the indoor unit, the evaporator coil allows the cold refrigerant to absorb heat from the indoor air. A fan blows warm air over the coil, and the refrigerant inside absorbs the heat, cooling the air. As the refrigerant heats up, it evaporates back into a gas.


5. Fan: 

AC systems typically have two fans—one in the indoor unit and one in the outdoor unit. The indoor fan circulates room air across the evaporator coil and back into the room. The outdoor fan blows air over the condenser coil to help expel heat from the refrigerant.

UPDATE: JAMB to reschedule 2025 UTME for candidates affected by technical issues in southeast, Lagos

 


The Joint Admissions and Matriculation Board (JAMB) has said it would reschedule 379,997 candidates affected by technical glitches in the five states of the South East and Lagos to retake the Unified Tertiary and Matriculation Examination (UTME).

Registrar of JAMB, Prof. Is-haq Oloyede, made this known in an ongoing press briefing in Abuja on Wednesday.

He said, “206,610 in 65 centres were affected in Lagos and 92 centres in the Owerri zone comprising 173,387 candidates in the five states of the South East were affected.”

Oloyede, who took responsibility for what he described as a “sabotage” of the 2025 UTME, said the affected candidates will start getting text messages from the Board starting Thursday. 

He added, “The affected candidates will start getting text messages for rescheduling starting from tomorrow.

“I apologise, I take full responsibility.”

Of the 1.9 million candidates who sat the UTME, over 1.5 million reportedly scored below 200 out of the maximum 400 marks, raising concerns across the education sector.

More Details shortly…

BREAKING: JAMB admits to errors in 2025 UTME Results

 

The Joint Admission and Matriculation Board on Wednesday finally admitted to errors which affected the performance of students during the 2025 Unified Tertiary Matriculation Examination.

The Registrar of the Board, Prof. Ishaq Oloyede admitted to this during an ongoing press briefing in Abuja.

“What should have been a moment of joy has changed due to one or two errors,” Oloyede said.

The UTME is a critical prerequisite for admission into tertiary institutions in Nigeria. It tests candidates in four subjects, including the compulsory Use of English, with the other three drawn from their proposed field of study.

Of the 1.9 million candidates who sat the UTME, over 1.5 million reportedly scored below 200 out of the maximum 400 marks, raising concerns across the education sector.

According to the examination agency, a total of 1,955,069 results were processed, out of which only 4,756 candidates (0.24 per cent) scored 320 and above, considered top-tier performance, while 7,658 candidates (0.39 per cent) scored between 300 and 319, bringing the total for those who scored 300 and above to 12,414 candidates (0.63 per cent). 

Some affected candidates threatened to initiate a lawsuit against JAMB.

Details later…

 

Why is the intake valve larger than the exhaust valve?


1. The intake valve allows the air-fuel mixture to enter the combustion chamber. A larger valve ensures more mixture enters, boosting engine power and efficiency.


2. Exhaust gases are expelled after combustion. Since they’re pushed out by high-pressure forces, a smaller exhaust valve can still handle the job efficiently.


3. Exhaust valves face extreme heat. Smaller size helps manage this heat more effectively and allows room for stronger materials or cooling techniques.


4. Larger intake valves improve volumetric efficiency (how much air the engine can take in), directly impacting performance.


5. Engine designers balance valve sizes for durability, efficiency, and performance, making the intake valve larger is part of this fine-tuning.


In short: A bigger intake valve = better breathing, better power.

UTME 2025 RESULTS: We may review results - Says JAMB (Press Statement)


 

The Joint Admissions and Matriculation Board has announced a review of the 2025 Unified Tertiary Matriculation Examination results following a wave of “unusual complaints” from candidates after the results were released on Friday

RE: PUBLIC COMPLAINT REGARDING THE RELEASE OF THE 2025 UTME

The Joint Admissions and Matriculation Board (JAMB) acknowledges the significant volume of unusual complaints following the release of the 2025 Unified Tertiary Matriculation Examination (UTME) results, which were officially published last Friday. In response, the Board is fast forwarding its annual system review—a comprehensive post-mortem of the examination process that is conducted each year months after the exercise.

The Board’s annual review encompasses three key stages: registration, examination, and result release. During the examination phase, JAMB ensures that every candidate is afforded the opportunity to sit for the test. Should any technical issues arise, the Board reschedules the examination for affected candidates without hesitation.

We are particularly concerned about the unusual complaints originating from a few states within the Federation. We are currently scrutinising these complaints in detail to identify and rectify any potential technical issues. To assist in this process, we have engaged a number of experts, including members from the Computer Professionals Association of Nigeria, Chief External Examiners, who are heads of tertiary institutions, the Educational Assessment and Research Network in Africa, measurement experts, and Vice Chancellors from various institutions. If it is determined that there were indeed glitches, we will implement appropriate remedial measures promptly, as we do in the case of the examinations themselves.

Anti-lock braking systems (ABS): How Your Brakes Adapt to Prevent Wheel Lock-Up

 



In-Depth Look at ABS: How Your Brakes Adapt to Prevent Wheel Lock-Up


1. ABS Sensors: The ABS system utilizes sensors placed on each wheel to monitor their rotational speed.


2. Wheel Speed Comparison: The ABS control module constantly compares the speed of each wheel. If it detects a significant difference in speed between wheels, it indicates a potential wheel lock-up situation.


3. Hydraulic Control: When a wheel lock-up is detected, the ABS control module activates a hydraulic system connected to the brakes.


4. Brake Pressure Modulation: The hydraulic system rapidly modulates the brake pressure to the affected wheel(s) by releasing and reapplying the brake pressure. This action is done through solenoid valves in the hydraulic unit.


5. Pulsating Brake Pressure: By rapidly modulating the brake pressure, the ABS prevents the wheels from fully locking up. It allows the driver to maintain steering control and maneuverability while braking.


6. Anti-lock Effect: The rapid pressure modulation creates a pulsating effect felt through the brake pedal. This indicates that the ABS is actively working to prevent wheel lock-up.


7. Continuous Monitoring: The ABS system continuously monitors the wheel speeds, making adjustments as necessary to ensure optimal braking performance.


By preventing wheel lock-up and maintaining traction with the road surface, the ABS enhances braking efficiency and control, particular lay in emergency or slippery situations. It allows the driver to steer while braking, reducing the risk of skidding and improving overall safety.

Car Fuel System Explained: Key Parts and How They Work Together for Engine:



Car Fuel System Explained: Key Parts and How They Work Together for Engine: 


The fuel system in a car is designed to store, filter, and deliver fuel efficiently to the engine for combustion. Here are the main components and their roles:


1. Fuel Tank:

The fuel tank stores gasoline or diesel. It is typically made of metal or plastic and has internal baffles to reduce fuel sloshing during movement. It’s the starting point of the fuel delivery system.


2. Coarse Fuel Filter (Pre-Filter):

Located near or inside the fuel tank, the coarse filter removes large impurities and debris before the fuel enters the pump. It helps protect the fuel pump from damage.


3. Electrical Fuel Pump:

The electric fuel pump draws fuel from the tank and pushes it through the system under high pressure. It is usually located inside or near the fuel tank and is controlled by the vehicle's electronic control unit (ECU).


4. Fuel Pipeline:

Fuel lines or pipelines transport fuel from the tank to the engine. They are designed to handle pressure and resist corrosion. Both metal and rubber hoses are used.


5. Fine Fuel Filter:

Positioned after the fuel pump, the fine fuel filter removes tiny contaminants that could clog fuel injectors or damage the engine. Clean fuel is essential for proper engine performance.


6. Pressure Regulator:

The fuel pressure regulator maintains consistent fuel pressure in the system. It ensures the engine receives the correct amount of fuel regardless of driving conditions or load.


7. Nozzle Rail (Fuel Rail):

The nozzle rail is a metal tube that distributes fuel evenly to all injectors (fuel nozzles). It maintains constant pressure across all injectors.


8. Fuel Nozzle (Injector):

Fuel nozzles or injectors spray a fine mist of fuel into the combustion chamber or intake manifold. The ECU controls the timing and amount of fuel each injector delivers.

Recognizing the symptoms of a failing alternator and fixing the underlying issues can help prevent you from getting stranded with a dead battery. Regular maintenance and replacing the alternator when needed are important for reliable vehicle operation.

Causes of brake pedal hardening

 



* Damage to the brake assist hose

The brake assist hose connected to the "servo" must be checked regularly, as damage to this hose or its movement from its place leads to hardening of the brake pedal, which leads to accidents


* Damage to the servo

The servo has an important function in the car as it helps reduce the effort resulting from pressing the brakes, and when the servo is damaged, the brake pedal is exposed to hardening, so when it is damaged, it must be changed quickly


* Fluid leakage

Brake fluid leakage leads to a loss of pressure inside the brakes, which leads to the pedal hardening, but at a low level as the pedal starts very soft until it ends at the bottom hardened and the brake effect is often very weak and the car is unable to stop


* Accumulation of dirt and sediments

Sediments can accumulate in different parts of the brake system, and their effect on the pedal hardening varies according to the presence of these sediments


* Malfunction of the hydraulic valves

The brake system has parts that control the distribution of hydraulic pressure force on the wheels, in order to maintain the balance of the car, and these parts are often found in the anti-lock system ABS, and if these valves are damaged, a malfunction occurs in the hydraulic pressure, which leads to the pedal becoming stuck


* Pedal damage

The pedal itself may be exposed to mechanical damage in its movement outside the hydraulic system, such as the presence of an object that prevents it from moving normally or damage to the pedal spring or mounting screws


* Brake fluid shortage

When the brake fluid is low, the pedal will become stuck and you will notice weak brakes due to the lack of brake fluid, which prevents the brakes from working properly.

HOW TO DEACTIVATE THE IMMOBILIZER FROM YOUR ECU (COMPLETE GUIDES)

HOW TO DEACTIVATE THE IMMOBILIZER FROM YOUR ECU (COMPLETE GUIDES) UNLOCKING THE SECRET



In today’s automotive world, the immobilizer system plays a crucial role in vehicle security, preventing unauthorized access by disabling the engine unless the correct key is present. However, there are circumstances where deactivating the immobilizer becomes necessary. Whether it's due to a malfunctioning system, lost keys, or modifications such as engine swaps, understanding how to disable this security feature can be essential.

This guide, "How to Deactivate the Immobilizer from Your ECU," is designed to provide a comprehensive look into the process. We will explore the reasons behind immobilizer deactivation, the technical steps involved, and the potential risks and legal considerations that come with it. This guide is intended for those with a strong background in automotive electronics, as the task requires precision and expertise.

Deactivating an immobilizer is not a decision to be made lightly, and this guide aims to equip you with the knowledge needed to approach this process responsibly and effectively. Whether you’re a professional technician or an advanced DIYer, this guide will serve as your roadmap to safely and successfully navigating the complexities of immobilizer deactivation.


WHAT IS THE IMMOBILIZER SYSTEM AND WHY IS IT IMPORTANT?

The immobilizer system is a security feature that prevents your car from starting without the right key. The key has a small chip inside that sends a code to the ECU when you insert it in the ignition. The ECU checks the code and if it matches, it allows the engine to start. If the code does not match, the ECU blocks the engine and the car will not start.


The immobilizer system is important because it protects your car from theft. Without the right key, no one can start your car, even if they break into it or hotwire it. The immobilizer system also helps your car run better and save fuel, by adjusting the air-fuel ratio and the ignition timing according to the oxygen level in the exhaust gas.

The immobilizer system is usually installed in the factory, but some car owners may choose to add it later.


THERE ARE DIFFERENT TYPES OF IMMOBILIZER SYSTEMS, SUCH AS:

(1): PASSIVE IMMOBILIZER:

This type of immobilizer activates automatically when you turn off the ignition. You do not need to do anything else to activate it.


(2): ACTIVE IMMOBILIZER:

This type of immobilizer requires you to press a button or use a remote control to activate it. You need to do this every time you park your car.


(3): SMART KEY IMMOBILIZER:

This type of immobilizer uses a smart key that you can keep in your pocket or purse. The car will recognize the smart key when you are near it and will unlock the doors and start the engine automatically.


HOW TO DEACTIVATE THE IMMOBILIZER FROM YOUR ECU?

There are many reasons why you may want to deactivate the immobilizer from your ECU. For example, you may want to:

Troubleshoot some engine problems that may be caused by the immobilizer system.

What is the Timing Mark in the Engine and Why it's Necessary?

 


A timing mark is an indicator used for setting the timing of the ignition system of an engine, typically found on the crankshaft pulley (as pictured) or the flywheel.


These have the largest radius rotating at crankshaft speed and therefore are the place where marks at one-degree intervals will be farthest apart.


On older engines, it is common to set the ignition timing using a timing light, which flashes in time with the ignition system (and hence engine rotation). Shining the light on the timing marks makes them appear stationary due to the stroboscopic effect.


The ignition timing can then be adjusted to fire at the correct point in the engine's rotation, typically a few degrees before the top dead center and advancing with increasing engine speed. The timing can be adjusted by loosening and slightly rotating the distributor in its seat.


Modern engines usually use a crank sensor directly connected to the engine management system.


The term can also be used to describe the tick marks along the length of an optical mark recognition sheet, used to confirm the location of the sheet as it passes through the reader.


See, for example, U.S. Patent 3,218,439 (filed 1964, granted 1965), which refers to a timing track down the left side of the form, and U.S. Patent 3,267,258 (filed 1963, granted 1966), which refers to a column of timing marks on the right side of the form.

The image illustrates a single-plate clutch system used in vehicles with manual transmissions.


Here's a breakdown of what the image shows:

Top Diagram (Schematic View):

 * It shows a cross-section of the clutch assembly and its connection to the engine and gearbox.

 * Key components are labeled:

   * Flywheel: Attached to the engine's crankshaft.

   * Clutch disc: Has friction linings and a splined center hub that connects to the transmission input shaft.

   * Pressure plate: Part of the pressure plate assembly (which also includes the clutch cover, fulcrum ring, and diaphragm spring). It presses against the clutch disc to engage it with the flywheel.

   * Diaphragm spring: Provides the force to engage the clutch.

   * Clutch fork: Actuated by the clutch pedal mechanism to move the thrust bearing.

   * Thrust bearing (Release bearing): When the clutch pedal is pressed, the fork moves this bearing against the diaphragm spring, releasing pressure on the clutch disc.

   * Transmission input shaft: Connects to the gearbox and receives power from the engine when the clutch is engaged.

   * Pilot bearing: Located in the center of the flywheel, it supports the end of the transmission input shaft.

   * Crankshaft: The rotating output shaft of the engine.

   * Clutch pedal: Operated by the driver to engage and disengage the clutch.

   * Bolt: Used to secure the clutch assembly to the flywheel.

   * Splines: Grooves on the transmission input shaft that mate with the clutch disc hub.

Bottom Image (Exploded View and Contextual View):

 * Exploded View: Shows the individual components of the clutch system separated: Flywheel, Clutch disc, Pressure plate, and Cover.

 * Contextual View: Shows the clutch assembly located between the Engine and the Gear box (Transmission). It also labels the Mechanism, Cover, Clutch disc, Pressure plate, and Diaphragm spring.


In essence, the image explains how a single-plate clutch works to connect and disconnect the engine's power from the transmission, allowing the driver to change gears. 

When the clutch pedal is released, the diaphragm spring forces the pressure plate to clamp the clutch disc against the flywheel, transmitting power. 

When the clutch pedal is pressed, the thrust bearing releases this pressure, allowing the clutch disc to spin freely and disconnecting the power flow.

10 Essential Engine Parts You Must Know: Functions Explained and Their Uses

An engine is a complex machine made of various components working together to convert fuel into mechanical power. Here are the most important parts and their functions:


1. Piston:


The piston moves up and down inside the cylinder, compressing air-fuel mixture and transferring combustion force to the crankshaft via the connecting rod.


2. Connecting Rod:


This rod connects the piston to the crankshaft. It converts the piston's up-and-down (reciprocating) motion into rotational motion.


3. Crankshaft:


The crankshaft receives motion from the connecting rod and spins to transfer power to the transmission and wheels. It's a vital rotating component.


4. Camshaft:


The camshaft controls the opening and closing of intake and exhaust valves. It rotates in sync with the crankshaft and uses cam lobes to press on lifters or rocker arms.


5. Flywheel:


Attached to the crankshaft, the flywheel stores rotational energy and helps smooth out engine vibrations. It also assists in starting the engine and connecting to the clutch in manual vehicles.


6. Oil Sump (Oil Pan):


Located at the bottom of the engine, it stores engine oil. The oil is circulated through the engine to lubricate, cool, and clean moving parts.


7. Drive Belt (Serpentine Belt):


This belt drives accessories like the alternator, water pump, power steering pump, and air conditioning compressor. It's powered by the engine's rotation.


8. Cylinder Block:


The main structure of the engine where the pistons move. It houses the cylinders, coolant passages, oil galleries, and sometimes the crankcase.


9. Cylinder Head:


Sits atop the cylinder block and contains the combustion chamber, valves, and often the camshaft (in OHC engines). It seals the top of the cylinders.


10. Valves (Intake & Exhaust):


These open and close at the right time to allow air-fuel mixture in and exhaust gases out of the combustion chamber.

The Complete Guide to MAF Sensors: Diagnosis, Maintenance, and More

 The Complete Guide to MAF Sensors: Diagnosis, Maintenance, and More



At the heart of every modern engine lies a mass airflow sensor, a vital component responsible for measuring the volume and density of air entering the engine. By accurately sensing airflow, MAF sensors enable the engine control unit (ECU) to adjust fuel injection rates, ensuring optimal combustion and performance.


Your car's engine is a complicated machine, and just like any complex system, it relies on precise measurements to function optimally. The mass airflow (MAF) sensor plays a critical role in this symphony of efficiency, ensuring the engine receives the correct amount of air for proper combustion. But how exactly does this sensor work, and how can you tell when it's malfunctioning? This comprehensive guide delves into the world of MAF sensors, empowering you to understand their function, identify potential issues, and keep your engine running smoothly.

The Master of Airflow:

Imagine a tiny conductor meticulously measuring the air entering your car's engine. That's essentially the job of the MAF sensor. Located in the air intake system, this sensor calculates the mass (amount) of air flowing into the engine. This information is crucial for the  Engine Control Unit (ECU), the car's computer brain, to determine the ideal amount of fuel to inject for optimal combustion.


Why the Mass Airflow Sensor is Important

The MAF sensor plays a vital role in maintaining a healthy balance between engine performance, fuel efficiency, and emissions:


Precise Air-Fuel Mixture: By accurately measuring airflow, the MAF sensor helps the ECU precisely control the fuel injection process. This ensures a balanced air-fuel mixture, leading to:

Optimal Engine Performance: The correct air-fuel ratio allows for complete combustion, maximizing power output and smooth operation.

Improved Fuel Economy: A balanced mixture ensures the engine doesn't waste fuel, translating to better gas mileage.

Reduced Emissions: Proper combustion minimizes harmful pollutants released into the environment.


Signs of a Faulty Mass Airflow Sensor

Just like any other component, MAF sensors can wear out or malfunction over time. Here are some telltale signs that your MAF sensor might need attention:


Illuminated Check Engine Light: This is the most common symptom of a MAF sensor issue.

Rough Idling and Engine Misfires: An incorrect air-fuel mixture due to a faulty sensor can cause these problems.

Reduced Power and Acceleration: The engine might struggle to deliver full power if it's not receiving the right amount of air.

Increased Fuel Consumption: A malfunctioning MAF sensor can lead to a richer fuel mixture, resulting in poorer gas mileage.

Black Smoke from Exhaust: In rare cases, a very rich mixture can cause black smoke to be emitted from the exhaust.

Cleaning the Mass Airflow Sensor


In some cases, a dirty MAF sensor might be recoverable. Here's a crucial point: only use MAF sensor cleaner specifically designed for this purpose. Regular compressed air cleaning is generally not recommended as it can damage the sensor's delicate components.

Cleaning Procedure (Always refer to your specific vehicle's repair manual for detailed instructions):


Locate the MAF sensor: Consult your repair manual for the sensor's location in your vehicle.

Disconnect the electrical connector.

Carefully remove the sensor using the appropriate tools.

Spray the sensor element with MAF cleaner according to the product instructions.

Allow the sensor to dry completely before reinstalling.

Important Note: If the sensor is visibly damaged or cleaning doesn't resolve the issue, replacement is necessary.

Testing the Mass Airflow Sensor: A Step-by-Step Guide (General)

While specific procedures can vary depending on your vehicle's make and model, here's a general breakdown of how to test a Mass Airflow (MAF) sensor:


Safety First! Before starting, ensure your engine is cool and the car is turned off. Park on a level surface and engage the parking brake.


Step 1: Visual Inspection

Locate the MAF sensor. It's typically positioned in the air intake system, often near the air filter housing. Refer to your car's repair manual for its exact location.

Once you've found it, carefully inspect the sensor for any physical damage like cracks, chips, or loose connections.

Look for any signs of debris or contamination on the sensor element (the wire or mesh inside the sensor). Avoid touching the


Step 2: Checking Sensor Readings (Requires a Scan Tool)

If a visual inspection reveals no obvious damage, you can use a scan tool to retrieve live data from the MAF sensor. A scan tool is a handheld diagnostic device that plugs into your  car's OBD-II port (usually located under the dashboard).


With the scan tool connected and the car turned on (but not running), follow the tool's instructions to access the live data stream.

Look for the MAF sensor readings, typically displayed in grams per second (g/s) or kilograms per hour (kg/h).

Consult your car's repair manual for the expected MAF sensor readings at idle ( engine running but not in gear). Deviations from the expected range might indicate a problem.

Step 3: Voltage Checks (For Advanced Users)

This step is optional and requires a multimeter and a repair manual for specific instructions. It's recommended for experienced users comfortable working with electrical components.


Using the multimeter, measure the voltage output of the MAF sensor according to your car's repair manual.

Compare the measured voltage with the specified values in the manual. Significant deviations might suggest a faulty sensor.

Important Note: These are general guidelines. Always refer to your car's repair manual for specific instructions on testing the MAF sensor for your vehicle. If you're uncomfortable with any of these steps, it's best to consult a qualified mechanic.


Swapping Out the Mass Airflow Sensor

If a faulty MAF sensor is confirmed, replacing it is typically the recommended course of action. The replacement process generally involves:


Locating the sensor: The MAF sensor is usually situated in the air intake system, often near the air filter housing.

Disconnecting electrical connectors and removing the sensor.

Installing the new sensor and reconnecting the electrical connectors.

Clearing any trouble codes stored in the ECU.

How Long Does a Mass Airflow Sensor Last?

There's no one-size-fits-all answer to this question. MAF sensor lifespan can vary depending on driving conditions, air quality, and overall vehicle maintenance. Generally, they can last anywhere from 50,000 to 150,000 miles.

WHY MY CAR STARTS THEN DIES AFTER A SECOND (Possible Fixes)



HAVE EVER WONDERED WHY YOUR CAR START, THEN AFTER A WHILE IT GOES OFF? 

If your car engine dies a few seconds after it starts, it can be due to a number of different reasons. Anything from the electrical system to the fuel system can cause this problem. In most cases, the problem isn’t hard to fix and you can get the engine running with little effort. However, it is also important to make sure the underlying cause is identified and resolved for a permanent solution.

In this article,I will discuss some of the common reasons why your car starts for a second then dies immediately. 

WHY MY CAR STARTS THEN DIES AFTER A SECOND

There could be several reasons why your car starts then shuts off immediately. Some of them include: 

🔧Faulty battery

🔧Lack of fuel

🔧Faulty spark plugs

🔧Anti-theft alarm system

🔧Faulty fuel injector

🔧Clogged fuel filter

🔧Faulty exhaust gas recirculation (EGR) valve

🔧Bad engine control unit (ECU)

🔧Dirty or faulty MAF sensor

🔧Vacuum leak

🔧Bad idle air control valve (IAC)

🔧: FAULTY BATTERY:

A classic reason why your car starts for a second then dies is battery depletion. The car needs electricity from the battery to start. However, if your car starts then sputters and shuts off immediately, then the fault could be a lack of charging or a damaged battery. It may happen when the battery has enough power to start and an alternator generates a minimum of electricity to keep the car running. 

FIXES:

A battery change might fix the problem. Have assistance or the workshop check whether or not the battery has power and, if not, replacing it will resolve the fault. Keep a car maintenance checklist to avoid getting stuck while driving.

🔧: LACK OF FUEL:

The most common reason your car starts but then dies immediately is because of a lack of fuel in the engine. This often happens because there is a small amount of fuel in the fuel rail, which helps to start the engine. However, there is no fuel pressure to keep the engine running.

FIXES:

The lack of fuel is however quite easy to locate. You can connect a fuel pressure gauge to identify the pressure. You can also use some fuel-saving devices to improve fuel economy.

🔧: FAULTY SPARK PLUGS:

Spark plugs create the spark that allows the vehicle to burn fuel. Dirty or worn spark plugs are one of the most common reasons why a car starts but won’t stay running. As the electrode wears, the voltage required to create the spark and ignite the fuel increases. This may require you to crank the engine long before it starts.

If the spark plugs are faulty, the ignition will fail and the car starts then shuts off after a few seconds. This is why it is important to know the symptoms of a bad spark plug. 

FIXES:

Here is what to do when your car starts then dies due to faulty spark plugs. Simply, replace the worn-out spark plugs with new ones as they play a significant role in combustion.

🔧: ANTI-THEFT ALARM SYSTEM:

Another common reason that a car runs a few minutes then dies can be a problem with a theft alarm system. When the anti-theft system is activated, the car doesn’t send power to the fuel pump, which creates fuel pressure in the fuel rail. This will start the car for a few seconds but not for a longer period.

FIXES:

Turn on the ignition to switch off the anti-theft alarm system. Doing so should turn off the key symbol on your car dashboard warning light. If not, then lock your car again and unlock it to start again. If it’s still on, there may be a problem with your car key.

🔧: FAULTY FUEL INJECTOR

Fuel is injected under high pressure into the combustion chamber using fuel injectors. The job of the fuel injectors is to regulate the exact amount of fuel that enters the combustion chamber.

If a fuel injector fails, it can cause the engine to run with fewer cylinders and also lower fuel pressure if one is stuck open.

FG suspends scholarship programme for 5 years

 


The federal government has announced a five-year suspension of the Bilateral Education Agreement (BEA) scholarship programme, citing the need to promote local student development and improve access to quality education within Nigeria.

Dr Olatunji Alausa, the Minister of Education, announced a comprehensive review of academic programmes offered abroad under the scheme.

Folasade Boriowo, the Director of Press and Public Relations, saidd in a statement that the review concluded that all courses available through the BEA scholarship were now being offered in Nigerian institutions, many with enhanced quality.

“We have carefully reviewed all courses our citizens pursue abroad. Every single one is now offered here at home,” Alausa said.

He emphasised that while the government encourages Nigerians to study locally, the suspension does not prevent individuals from pursuing private education overseas.

“We must be fair and equitable to every citizen. The government currently spends significantly on tickets, stipends, and other costs to send students abroad for education they can now access at home, often of better quality,” he said.

Dr Alausa clarified that the federal government would continue to accept fully funded scholarships from BEA partner countries, provided they cover tuition, accommodation, travel, living expenses, healthcare, and a minimum monthly stipend of $500, with no financial obligation to Nigeria.

The minister also said the suspension would not affect other federal scholarship initiatives. These include the Nigerian Scholarship Award for students in public universities and polytechnics, the Education Bursary Award for undergraduates studying education, and the Presidential Scholarship for exceptional ex-NYSC corps members.

He equally highlighted improvements to the Nigerian Student Loan Programme, which now offers enhanced financial support to students enrolled in local tertiary institutions.

All current BEA scholarship beneficiaries will continue to receive full government support until the completion of their studies and return to Nigeria, Dr Alausa confirmed.

Reaffirming the federal government’s commitment to equitable access to education, the minister said efforts were underway to expand local scholarship opportunities and ensure that “no dream is delayed or denied”.

The BEA programme, established through diplomatic partnerships, has enabled Nigerian students to study in countries such as China, Russia, Algeria, Hungary, Morocco, Egypt, and Serbia.

Host countries typically provide tuition, accommodation, and stipends, while the Nigerian government covers take-off grants, supplementary allowances, and return travel.
