Having problems with your Cars & Trucks ?

2001 Grand Prix stalls at random times?

\015 Hi there, I have a 2001 Grand Prix special edition with 160,000km. I recently bought it knowing it was having issues, and was told the problem was in the fuel pump. The car would sputter intermittently and sometimes even stall. The car fires right back up after it dies. I changed the fuel pump and the problem continued. I have no diagnostic light on my dash to run any tests. Any ideas? It seems to more commonly stall when riding over a bump onto a driveway or when i begin braking when coming off the highway. Thanks!\012 Wilson Fink\015 Posted / edited by AnonymousUser on : 06-07-2020

Answers :

I would start by checking your wiring connections at fuel pump, check for corrosion, or loose fir male to female, then I would check your ground wires for fuel pump and engine also. you could have a wire hanging by a thread in the fuel harness or a ground wire that is making poor connection and when you hit the brakes possibly pulling ground for brake lights from fuel pump circuit, got to be something fairly simple but intermittent problems are the hardest to find, also check fuel pump relay and connections it plugs into. if can't visibly see anything then time to get the dig. volt meter and start checking wires from point A to Point B this will take time but it's about your only chance of figuring it out.
