I have a 2001 Pontiac Grand Am GT 3.4 V-6, I had a no start situation and determined that the
fuel pump was not working. I replaced the fuel pump and checked it by hooking a jumper directly
from battery before installing, the fuel pump worked fine.
After installing the gas tank I am still getting no fuel from the fuel pump, I have checked and
replaced the fuel pump relay and checked all fuses, including. The car will start and run with
starting fluid until the starting fluid runs out and then dies. What else can I check, could the PCM
be bad Thank You.
It's possible you could have ruined the fuel pump by running outside the tank by hooking it up to
a battery. Try checking for power and ground at the fuel pump connector, and if you have it, then
you have a bad fuel pump. If you don't have power there while cranking or the 2 second prime
with the key in the 'on' position, then you have a wiring issue or some other problem that is killing
your fuel signal.
Things that can kill the fuel signal are a bad PCM, corroded or broken wiring, a theft deterrent
problem, etc. Since it runs on carb spray, you obviously have spark, air, and compression. I
would assume that the crank sensor and ignition module are ok, otherwise you probably wouldn't
have spark. You should check and make sure the theft or security light isn't flashing or on steady
after trying to start the car.
That is a common problem on your vehicle and a theft deterrent issue, like a passlock sensor,
would stop the fuel delivery signal. I'd start by re-checking the fuel pump just to make sure you
have power back there and you didn't smoke it when jumping it while not submerged in gas.
