why dose my car delay cranking after pumping gas
When you fill your gas tank, a lot of fumes build up in the fuel tank and usually excess fumes come out of the fuel filled tube and out to atmosphere or into a recovery system in the fuel pump handle.
You may have a purge valve that is not sealing correctly and the fumes are going into your engine causing your engine to be flooded with fumes while you are refueling. You can help your car start by holding the throttle wide open to get extra air into the engine to get it started, and then letting off the gas once it starts. This is only a way to get it started after refueling until you get the purge valve replaced to fix the problem.
Be more clear about what happens after you fill up:
- The engine turns over (rrr-rrr-rrr) but does not start and run when you turn the key to Start.
Or - The engine does not turn over. After some time has passed and you again turn the key to Start, it does turn over and start and run.
