Why Does My Car Have a Hard Time Starting After I Put Gas in It?

December 7, 2023

There are a lot of different components that work together to start your car. And when one of those components fails, your engine can’t turn over and start. This is what happens when your car has a hard time starting after you put gas in it.

This problem can be caused by a few things. First, you could have bad fuel. This type of gasoline is contaminated with many residues and inclusions that cause your engine to not combust properly. The fuel filter and the tiny filters in your injectors will become clogged with these substances. This can also lead to a failing ECU, which will set your Check Engine light on.

Another possible culprit is a stuck EVAP purge valve. When this valve remains open, excess fuel vapors will flood the engine, causing it to have trouble starting. If this is the case, you will need to replace the valve to fix your car’s starting issues after refueling.

A last potential issue is a dead or weak battery. The battery is responsible for providing power to the starter motor, which in turn turns over your crankshaft and draws a mixture of air and fuel into the cylinders to start your engine. If your battery is old or weak, it won’t be able to provide the necessary power to the starter motor and other components, and your car will have a hard time starting when you fill up. This is why it’s important to get your battery tested and replaced if needed.
