Pontiac Problems? Ask a Mechanic for Answers ASAP
Thank you very much for your expert advice!!
If positive ful pressure remains constant from the fuel pump, could a bad EGR valve create a vacuum producing the sypmtoms I described?
The car starts and remains running for a while then cuts off. Fuel pump was checked and positive fuel pressure remained constant when running and did not wane. All lines were checked for vacuum leaks none noted. Checking EGR valve when car cools down! Anything else we can check? How could we check the computer module for proper functionality?
South Dakato, hell its warm in Jersey compared to there! Do I need to pay another whole payment for the same answer!
Thank u very much for your time and patience!
Stay warm brother,
We drove the car on the highway, it did cut off after a while, and after 10minutes or less it started back up. The mechanic says the fuel pump has mainmaintained good pressure throughout, shether idling otr whe it cut off. Does this vehiclel hav ethe trational cap/rotor or coil packs?It lookis as if it has coil packs . Could tyhis be the cause? I know the mechanic chnaged the wires and plugs but not the packs . we c;leaned teh trermionals on the battery just in case. Buthe vehivle still cuts out. My son has said tht when it recently cutoff, while coasting to a spot he stepped on the accelerator and the car restarted back up before he came to a full stop. Do you sitill believe it is the pump or would you now start to lean towards the computer. Again, no codes or lighs have gone off!
