Why Would A Car Not Start After Filling Up With Gas? Misfires are a common problem in all engines, but they are particularly pesky in Audis. Potential causes include worn ignition parts (coils and spark plugs), lean condition (too much air, vacuum leak), rich condition (too much fuel, fuel presser, leaking injector) or a worn engine (carbon buildup or low compression).
Why does my car not start after getting gas? Most of the time, if your car suddenly will crank and not start after fueling, it is because of a failed fuel pump. The fuel pump in the fuel tank is kept cool with the fuel in the tank. If the fuel was very low, then the pump would get too hot and then when you add cool fuel into the tank that causes the pump to fail.
Why does my car sputter after getting gas? One of the most common causes of a sputtering engine is an issue with the vehicle’s fuel system—the filter, pump, and injectors. Since the fuel filter, pump, and injectors work together as part of one interconnected system, dirt and debris need only clog one part to cause the others to fail.
