2003 Pontiac Grand Am SE (2.2L Eng)
The vehicle stalls during use - speed is no matter. After successive stalls, I must let the car rest before it will start again. It's as if the alternator isn't working and I'm losing power, but both that and the battery test well.
Adding to concern, the fuel pump is only giving me 30lbs of pressure at fuel rail, which is starting the vehicle but not maintaining functioning. However, many others in internet-world have had the same problem, replaced the fuel pump ($260+labor) and have not fixed the problem.
Changed fuel filter last July; fuel pump was giving me 54 lbs pressure at fuel rail then.
Changed fuel pump relay last night - car idled for 30 minutes without fail, but it gave no increase the fuel pressure at fuel rail.
have the same problem?
