Question about 1996 Pontiac Sunfire
I can got to the store and back, it will run just fine. It idles just fine. But if I go to school, the store and then get gas...it will not start up. It just cranks over but doesn't start. Then you receive a varnished gas fume smell. You have to sit for about an hour or 1 1/2 hours and it will start up just fine again.
I have replaced the coil packs, spark plugs, and module. It still does the same thing. I am not a mechanic but it seems like maybe something that gets hot and then this makes it not start. I have had a diagnostic machine hooked up to it and the machine couldn't give the sales manager at the parts store a code, just a bunch of unfamiliar numbers (he said like it was written in foreign numbers).
Can you please help me better identify what might be the cause or at least start me out in a good direction as to where to start replacing?

Give me the year make and model, engine size and standard or auto trans? Sound like you have a fuel issue to me. Perhaps a faulty fuel injector(S). Let me know the specs...cheers!

Tips for a great answer:
Engine stalls or RPM
fluctuates at idle up and down or dies near idle.
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
