1999 Pontiac Grand Am Repair Question
Starts then dies, but will eventually stay running
The first thing i would check for is codes have you done that yet?Also do you have a multimeter to do some testing?you could have a bad coolant temp sensor it would make sense for your symptoms.
I don't have a reader for the newer stuff....Yet. It Does it hot or cold
Hi saturntech9. How about low oil level / pressure and the fuel pump is switched on by oil pressure? I don't know which years or models that applies to but sure sounds like how that system acted.

Hey Doc, The fuel pumps that are integrated into the fuel pump circuit are done so as redundant power supplies for the pump. The relay will pre-empt the oil sender, unless it is bad.

It wouldnt hurt caridodoc jhenriksen check your oil level see if its low.Also take it to a auto parts store like auto zone and have them scan the computer for codes.If you have any codes then let me know the exact code numbers not the code descriptions.Also a multimeter would be helpful to test things.
Oil level is good. I will get it scanned. I do have a mulitmeter.
Alright let me know about the codes and we will go from there.
No codes, fuel pressure kinda dances from low to high 40s as i crank it over and its trying to start.
Pull the fuel pressure regulator vacuum line off the nipple see if there is fuel coming out of the nipple.
Nope, its dry
