I own a 1988 Chevy Comaro with a 305 TBI. Sometimes, when the car is warm and you go to start it, it will flood over and not start. I believe my problem is excessive fuel pressure build up in the tank. If I release the fuel cap you can hear the air rush out and the tank even collapse from the pressure. Could this be forcing to much gas into the engine, why is the pressure building up, and is the car suppose to release the pressure itself?
P.S. When I removed the fuse to shut off the fuel pump, the car started and ran for a long time, poorly, but ran.
