problems after fillup

[ncaligst98]

everytime i am done filling my car with gas, i go to turn on my car starts up fine, but then the idle gets choppy and rough and car dies , and it will keep doning this everytime you go to start the car, the only way the car can remain on is if i turn the key and hold the gas petal down and rev it a little bit and the problem goes away. it happens with what ever amount of gas i put in, pressure tested the gas cap and its fine dont know the problem..... any ideas or info would greatly help thanks.

What kind of gas are you using. Are you using premium or not? Also do you just fill it up until the pump stops or do you keep squeezing every ounce out of it you can. If you are you are probably plugging your gastank vent and it isn't allowing gas to get sucked through the line's properly until it sucks some down. Try filling it up just before full next time.

Sounds like the classic vapor lock problem. Check your fuel pressure solenoid for proper operation. It raises the fuel pressure so fuel will not vaporize when engine is started while warm.
