Problem with my 2004 Pontiac Grand Prix
3800 v6
Repair work done prior = new tires, lined up,right sided CV joint
replacement and seal.
GM tech = anyone
question = car will click loud when gas is applied when driving. Also
occasional jerking of transmission on take off from stopped position but
trans fluid is @ right level.
SF:
Since the clicking noise started after the axle was replaced, it may not be
fully trans. There are several bulletins for transmission problems. From
input clutch to second clutch problem. Pressure control solenoid, valvebody
problems. Would need to be driven by a trans. tech to begin diagnosis.

Question:
1999 Pontiac Grand Prix.
Engine size = 3.8L V6 "VIN K".
Repairs for this problem = New battery, alternator, and fuel pump
question = My Grand Prix would run for about 10-15 mins. then it decided to stall. While it
was idling it would occasionally run up and down on the rpm. Then it would just stop out of
nowhere. I recently replaced the fuel pump but that didn't solve the problem. Then I
replaced the alternator and it was running fine for about 6-7 mins then I put the car in drive
and it died as soon as I did that. I put a new battery in too. Could this be my fuel pressure
regulator or my PCM? I tried to hook up a diagnostic tester to it but no codes showed up.

Answer:
You can check the fuel pressure regulator to see if it's leaking by removing the
vacuum hose that is attached to the top of the regulator. Usually, bad fuel
pressure regulators cause a hard starting condition and not a stalling problem,
but it's worth a check. The PCM probably isn't bad in this case unless you've
experienced some corrosion to the wiring, or have had water damage. A likely
candidate is the crank sensor. These are known to fail after warming up the
engine for a little bit, then cause it to die out. The car usually restarts, but will
die again. You may want to check the ignition module connector and give the
module itself the 'tap' test. A faulty mass airflow sensor could do this too, but
from what you describe I would start with a crank sensor.
