After filling the Gas tank of my '92 Camaro RS..I parked it and 2 hours later, I attempted to start my car...it started but it struggled to stay on...accelerating on its own...then it would shut down...as if choking....Istarted it again..turned on perfectly..but again struggled to stay on...doing the same thing...I tried pressing the gas..nothing.I cant get it going..the car starts fine but shuts down...My buddy brought a scanner over and the scannerdidnt read anything...checked theinjectors...everything good...checked air control valve...good...What else??

 

Is it the 305 tbi? if it is check the throttle positioning sensor! also take the gas cap off, and then put it back on, making sure it clicks. It's quite possible the cap is bad, if it cant create a vacuum, meaning the cap leaks it starves for fuel! being that the pump is in the tank. Try that and see, good luck.

 

Try to start it with the cap off. Maybe its something as simple as a clogged fuel filter.
