so i still havent replaced the pip sensor... but there is another problem i dont know if this has anything to do with the pip but the fuel pump relay switch and the ecm relay switch in the passenger side kick pannel gets really hot.. thats when it shuts off... wait two hours for it too cool down a bit and then it starts like nothing was wrong with it... anyone know what the heated relay switches could be from???

Im not good at wiring but I would think if its getting hot its shorting somwhere but since its DC voltage that would kill the circut for your fuel pump (If that is the source) and your pump wouldnt work at all. A few of these guys know this wiring stuff though hang in there.

my car does the exact same thing and im drawing blanks. ive traced every wire and replaced pip, tfi fuel pump. etc etc. no luck. check pin #22 on your ecm. check to see if its got a ground on it with key on and while cranking. it should have a ground on both those settings. after the car dies, i dont have any ground on #22, until it cools down again. so i have no ideal. just check that out. let me know.

here is what i have done... i replaced the tfi module,coil,cap,button,wires,plugs, a new ecm last year, fuel pump last year at the same time,fuel pump relay,ecm relay... and now im stuck.. i ran it for codes and got codes 26o,85o,10,14 i understand that 10 is a seperation code and 14 is the pip sensor... but 85 and 26 has something to do with the egr and.. the car has never had a smog pump 02 sensors or egr valve for the most part that i know of im going to post pictures here in a little bit of the problems
