It is embarrassing if your car won’t start after getting gas at the fuel station. But why? What is the reason behind this?

Are you worried that your car battery will die after getting gas in it? You thought your car was not starting or picking up the initial combustion because you were out of fuel or gas, but that is not due to the fuel pump.

This article will discuss why the car won’t start after getting gas and why the battery dies.

The car battery dies after getting gas.

Your car battery dies after getting because of the following reasons:

  • Weak battery
  •  Bad evap purge control valve
  •  Clogged fuel filter
  •  Defective fuel pump
  •  Bad alternator
  •  Bad starter motor
  •  Old spark plugs
  •  The bad fuel injection system
  •  Wheel lock

Now I will explain each problem in detail, so next time you won’t get irritated if your car battery dies after getting gas. Ok then, let’s start with the weak battery, which is the main cause of this matter.

Weak Battery:

Your car won’t start if it is not receiving much power from the battery. It may be because the car might have a dead battery, or it may have loose connections or a corroded battery.

The car battery usually has a lifespan of two to three years, and there are proper signs that show your car battery is going to die.

Replace the car battery if you are having trouble with accessories or feel the led light is dim. To make sure the connection is sturdy, you should check it for corrosion or wash it with baking soda and must check for other safety features.

Push the car away from the pumping gas station if you want a jump start on your car. Nothing that causes the spark should be done near the gas station.

The car can also have different issues for what car is not starting. Let’s suppose your car is out of the gas tank. You fill your car with gas, and it still needs to start. But don’t freak out! The reason why your car is not started after getting gas is listed below.

Your car gas tank is full, and you are ready to start the car, but the engine won’t run over.

Bad evap purge control valve:

Your car will only frequently start after getting gas because the evap purge control valve is stuck open. The excess air filter needs to be released from it, and the fuel pump’s nozzle cannot accommodate it.

The valve will be pushed straight into the intake manifold if stuck open. This will make it difficult to start after getting gas or fuel because too much fuel will enter the car’s engine when you crank it.

Clogged fuel filter:

Contaminated fuel pump through a filter called a fuel filter pump. Contamination is prevented from entering the car’s engine with fuel.

The fuel is cleaned before entering the car engine stalls from the fuel tank. The impurities from the fuel accumulate here and eventually block it.

It would be best to observe different symptoms before this issue blocks your car’s engine from starting, which is a sign of a clogged fuel filter. Fuel efficiency drops, and performance gradually deteriorates

. The car engine’s ignition cylinder won’t get much fuel from the fuel line it needs once the filter is completely blocked, leading to a no-start condition. The manufacturers recommend regular maintenance, including replacing your car filter.

Depending upon the owner’s manual, you might need to change it every twenty to thirty thousand miles. To keep the filter clean, we have to use premium fuel. Fuel filter results in a dead battery, also in a way that the fuel system may contain bad gas in the fuel lines.

Malfunctioning fuel pump:

The fuel pumps are submerged in the gas tank, ensuring it runs at a cool temperature. If you allow the fuel level to be too low, the fuel pump becomes hot, resulting in a damaged fuel pump.

The fuel pump must be functional to move the gas into the engine.

However, the damaged fuel pump will provide you with other symptoms before it goes out. Completely.

If the engine or car sputters while driving at high speed, you hear a whining noise from the tank, or the car stalls continuously, the fuel pump might be blamed.

You must monitor the pressure with a gauge to check the bad fuel pump. This is a difficult task, just as replacing it with a new one as often proves to be.

Bad starter motor:

You want to be able to start the engine if the starter motor malfunction. The starter motor starts the engine when you turn the key in the ignition system.

If this is the issue, you hear a clicking noise when you put the key in the ignition system.

Fortunately, there are methods to start the car with a bad fuel pump or starter motor. To get it past a stop, you might be banging on it. You might try banging on it if your car has a manual transmission.

Faulty alternator:

There are instances where you change the car battery but still experience the issue. It might be the issue with the gas pedal, and the car battery has died once more.

While the engine is running, the alternator is in charge of charging the battery.

Suppose the alternator is not working properly the battery runs out of power. To check the condition of the alternator, use a multimeter.

Check the voltage over it when the car engine is off and again when the engine is running. It will give 12 to 13 and 13 to 14 volts, respectively.

The issue with spark plugs:

To ignite the fuel-air mixture inside the fuel engine, spark plugs are required.

The engine may initially misfire when the spark plug wires become contaminated. However, this issue may also make it difficult to start the motor.

One component of the ignition system that is at fault is the spark plug. The spark plug wire, the ignition module, the circuits, and the ignition switch are additional considerations.

It would help if you replaced the spark plug according to the owner’s recommendation to avoid the issue.

Wheel lock:

If your car won’t start after getting gas, one of the reasons for this is the wheel lock. The car won’t start if you apply a wheel lock, and it causes the battery to die.

It is an anti-thief feature that prevents the vehicle. In this, the steering wheel is pushed back. Turn the ignition key in the inertia switch. The combustion chamber cannot start the catalytic converter but still forces the battery to do, and eventually, the car shuts.

What to do after the car won’t start after getting gas:

Sitting in your car at the gas station and your car is not starting is an embarrassing moment. There should be some useful actions that you can do to start the car:

  • Try to restart the car
  •  Check the battery connection
  •  Push the vehicle away from the car pump
  •  Jump-start if it is a dead battery.

Bad fuel injection system:

The most modern vehicle stalls have advanced fuel injectors or fuel injection systems. Sometimes the injectors get dirty, clogged fuel filters, or even completely fail and need to be replaced. The basic function of the fuel injectors is to supply the engine with the fuel in the fuel system. The injector sprays or injects the fuel into the fuel pump or in the fuel system through a small nozzle that creates fuel pressure so that the internal combustion chambers start the combustion to start the engine.

The fuel pump is responsible for fuel delivery, providing the fuel at the right time, amount, pressure angle, and spray pattern. It is also important that low-quality fuel is not injected. The engine control unit, or ECU, manages the fuel injector. Using sensors, ECU ensures that the fuel injector pumps the right amount of fuel spray at the right time in the fuel lines so that the right air-fuel mixture is created in the fuel line.

If something is wrong with the fuel injector, the car won’t start, or there will be poor engine performance. A faulty fuel pump or injector will either prevent the fuel from spraying into the engine or mess up the intervals at which it is supposed to be.

Let’s have a view about the bad fuel injectors that don’t create a fuel pressure regulator that results in the car won’t start.

Starting issues:

The car starting issue will only work if there is a proper fuel supply. If there is a bad gas injector or fuel injector, the fuel economy will disturb, and hence you may find difficulty in starting the engine even after putting gas fill.

Rough or idle engine car stalls:

It may be a bad fuel injector if you experience rough idle or the engine stall on low rpm. It is because there is a faulty alternator system that cause affects the fuel economy and creates a different mixture of air and fuel from the normal. You experience the rough or low idle as it doesn’t spray the exact amount of fuel vapor. If the rpm falls too low, the car will stall, and you will need to restart the car.

Engine vibrates:

If there is an insufficient fuel supply, the engine vibrates as it completes its cycle. If your car has a turbo engine or at turbo mood or even at high rpm, you need a perfect fuel delivery as it requires more fuel than a normal one which requires a larger fuel tank. The broken alternator or broken fuel pump can cause the injector not to supply enough fuel from the fuel tank, that in turn cause the vibration of the engine. The person next time has to face difficulty when the car starts.

Why does a car struggle after getting gas in it?

If you put gas in your car and your car does not start after getting gas, then it means there will be some other mechanical, electrical, or technical issues.

It may be due to the reason that the car battery is corroded battery or it may be due to the fuel filter. The fuel filter may have dirt or particles that cause difficulty starting the car.

Can low gas cause battery issues?

If your car runs out of gas, it will not affect its battery.

Fuel is used for the engine to start the car sputter. When your gas tank is empty car won’t start because there will be no raw material for its use.

In such a condition, if you repeat again and again try to start a car, its battery supplies current again and again, causing the battery to drain for a short instant as no engine works, resulting in no power generation through the alternator and thus, it affects your car battery.

Can the timing belt be the issue of not starting the car?

The timing belt is one of the issues that cause a car won’t start after getting gas, and the battery drains. In different tow truck and vehicles, the intake manifold and the battery dies due to a timing belt for different reasons.


So here are a few problems for the battery that a battery can face if you fill the gas cap after a long.

Several factors can affect the battery, including bad gas, car fuel pump, gas pedal ignition key, ignition cylinders, and fuel gauge, which are discussed above.

Besides, all these engine cylinders are also included, which can cause the battery to die after filling gas.
