What to do if your car won’t start after filling with gas

In most cases, the cause is a faulty purge valve that’s allowing gas vapor to flood the engine. To start the engine, press the accelerator pedal to the floor and hold it there while cranking the engine. That will enable the “clear flood” mode in the ECM and stop adding fuel while cranking.

To fix the won’t start after filling with gas

You have two options here:

  1. Replace the purge valve without doing any testing
  2. Clamp off the purge valve hose between the tank and the purge valve before filling the tank. If the engine starts right up, you’ll know the purge valve is leaking vapor into the engine during fillup.
