Car Struggles To Start After Putting Gas In: Causes & Fix

Any vehicle needs fuel to operate, and cars are no exception. Therefore, when the vehicle’s fuel level is too low, you must add more if you want to continue moving on your journey.

Usually, you can continue using the vehicle if you have filled the tank with gasoline or oil, but it is not always so simple. Because although it is pretty rare, we can still experience Car struggles to start after putting gas in. So why do we encounter this phenomenon? The answer will be in the article below.

Why Doesn’t The Car Start After Refueling?

In fact, many different faults come from factors outside and inside your Car. With problems from the outside environment, the most common will be fuel, such as too high or too low temperature causing volume change.

Another situation that is also likely to be encountered is decreased ignition ability due to bad weather. Even a reasonably rare but still possible case is that we use the wrong type of fuel for the vehicle.

With problems within the vehicle’s system, the leading causes are often concentrated in parts related to starting, such as the ignition and battery.

But sometimes, the fault lies in fuel-related details. And also, do not rule out the possibility that it originates from the key set and safety mechanism.

External Causes

Weather elements

Fuel, whether gasoline or oil, is a liquid and is still subject to the laws of physics. Therefore, if the weather is too hot or too cold to exceed a specific limit, there is a high chance that the fuel will also degrade, thereby affecting the vehicle’s ability to operate.

Problems related to carelessness

It is a fact that many people forget to close the gas tank cap before moving on, and some vehicles do not allow this to happen.

Some other cases come from users being too hasty in moving without noticing that the fuel pump nozzle is not removed from the Car. Although it sounds absurd, carelessness has a lot of impact in this case.

Fuel related problems

Each type of vehicle will be suitable for fuels with different parameters such as octane numbers. So if we use products that do not meet basic quality standards, even if the fuel tank is complete, the Car will not operate normally.

Another worse case is when we use the wrong type of fuel, such as gasoline instead of diesel fuel, and vice versa.

This mistake can bring about terrible consequences, not just the failure to start the Car. Typically, the damage of parts when encountering foreign elements causes breakage or jamming.

Steps To Check Before Looking Inside The System

To make sure that the problem causing the Car struggles to start after putting gas in is not caused by external factors, you need to check some of the actions below.

  • Check the fuel tank cap: The first thing that we need to note is whether the fuel tank has any problems. If the lid is not closed or the pump is not separated, the Car will be challenging to operate.
  • Check the fuel type: Make sure you have injected the correct type of fuel that the vehicle needs. Then consider whether the gasoline or oil being available is up to the vehicle’s standards and how complete the fuel tank is.
  • Move the car to a more relaxed or warmer place to ensure the temperature doesn’t affect the fuel inside.

The Causes Inside The Car System

The Causes Inside The Car System

Unlike external factors, the problem comes from operating the parts on the vehicle that require us to have a deeper approach to check and repair.

Dead or corroded battery, accumulator

Unusable batteries or accumulators are one of the most common causes of the vehicle failing to start. Because the igniter will no longer have enough energy to operate and no matter how much gasoline there is, the Car will not work.

Usually, this problem can be completely prevented with simple methods, but very few people check it before the problem occurs.

Generator broken

Another problem that also originates from the electrical system is the failure of the supporting generator.

If the battery and accumulator provide power to the system, the generator acts as a storage bank for excess to start the Car quickly and use features that require a lot of energy.

In other words, the system provides additional strength to activate the high-energy components.

Fuel filter too dirty

It’s not a good idea to let impurities like dirt and plaque go with the fuel into the internals. So manufacturers have added filters to suppress these negative factors.

But it is also this part that will prevent power from flowing through if the surface of the filter is too dirty.

More specifically, the impact of this incident is not only on the fuel transmission process but also on the components with the purpose of ignition.

Missing sparks

The vehicle can only be used when the mixture of air and fuel inside ignites, creating pressure and driving the pistol to work.

And if the mix of gas and energy cannot burn to a specific temperature, the other components cannot work either.

The central part responsible for creating a spark strong enough to ignite the mixture is the spark plug, so you will need to check if you have enough fuel and the Car does not operate.

Damaged fuel pump

The Car’s internal system needs to have enough pressure to control the fuel flow everywhere, be it from the tank to the cylinders or the filters. In addition, stress also plays a massive role in whether the fuel injection is strong or weak.

For the above reasons, the fuel pump, the central part that generates pressure, significantly impacts the vehicle’s ability to operate.

If there is damage during the operation of this part, indeed, gasoline or oil cannot move efficiently.

Faulty locking system

Carlock helps us to protect our vehicles from the evil intentions of harmful objects. But if the locking system itself has a problem, we will not start the Car even though the gas or oil tank is full.

Especially with classic versions like Chevy, you need to know how to remove the ignition lock cylinder chevy without a key to start the Car.


Car struggles to start after putting gas, which is a highly annoying situation that no one wants to encounter. So hope that the information in today’s article can help you identify the causes and have a remedy when you meet them.
