i posted on here saturday about my car quitting on me at the track, well they said it was the fuel pump, but it wasnt, now i dunno what it could be, the car will start up and run for about five minutes and then just die, and it wont start back until it gets back completely cold and then it does the same thing, i have no clue what it could be, can anyone please tell me whats wrong, the opti and waterpump was changed 12k miles ago so it shouldnt be that, so what could it possible be?

 

so youre aying that when it warms up it dies?? as in when it goes from open loop to closed loop (or vice versa, not sure which )?? are youre o2 wires grounded on the headers? burnt? just a suggestion

 

i havent checked them yet, but i will in the morning

 

your car is junk? dude keep your head up and don't get discouraged. try changing your coolant temp sensor. the one on the water pump. if that dosen't fix it, then see if it has any stored codes. any hot rod requires lots of attention, and you can't let little things like this get you down!

 

Dont worry man, we've alll been there.
