So I have a 97 Grand Prix GTP. It stalled last night and won't start again. I know for sure that its not out of gas, its not the battery, the alternator, or the starter. A few times within the last week it has stalled or it has started up but the start was weak and it would barely get going even if the gas was to the ground. Does it sound like it could be the fuel pump or do you know what it could be? Also, any clue how much it costs to have the fuel pump fixed?

Thought I would add a detail..yes when I tried to start it last night it was trying to start but it was making a sputtering sound but it will not start all the way. It has stalled and started back up but this time it won't.

Without checking the fuel pump pressure I couldn't say that was the problem. When you turn the ignition on can you hear the hum of the fuel pump? It'll only run for about 5 seconds so listen well. To me it sounds like your catalytic convertor is plugged. Usely if the fuel filter is plugged it will sputter and if the fuel pump was bad you wouldn't have been able to drive at all.

It could be the fuel pump, or might be a flaky ignition coil or coil pack. The right thing to do first is remove and clean your battery post connections to make sure that both your fuel system and ignition system are getting enough voltage and amperage to work the way they were designed to do. Also, check that the charging system is up to snuff as well. An engine that does not get a constant supply of voltage will inevitably weaken the operation of both fuel and ignition systems. When you are starting (cranking) a car, most of the battery power is diverted to the starter, which "draws" the most current. If there isn't enough reserve in the battery to spin the motor, fire the plugs, and supply power to your injectors all at the same time, the engine can't possible start. Also, stepping on the "gas" pedal on a modern car is a misnomer. In a fuel injected car, the "gas" pedal is really only adding air to the system, not fuel. They should really be calling it the "air" pedal. Also, be suspicious of the fuel pressure regulator. On older cars the diaphragm can rupture and not supply the proper fuel pressure. Good Luck!!

Food for thought is that if the plugs get worn down, the voltage jolt can start to bypass the spark plug internally and go around the outside. The spark could also penetrate the spark plug wire insulation too causing cylinders to miss.
It also could be in the fuel delivery. If you put a pressure tester on , you will see the pressure at the intake of the fuel injectors. A bad pump or clogged filter will not allow pressure to build up at the tester at all. Clogged fuel injectors will not allow the correct amount of fuel to pass into the intake manifold.
If I were to guess, it is probably just a fuel filter or spark plugs and maybe spark plug wires.
If it is in fact a fuel pump, replacement will be expensive. The part is about $300 new or probably $150 used. Also it would cost roughly $150 in labor for a shop to replace it. This is because the fuel pump is located inside the fuel tank.

More than likely, yes. It could also be a clogged fuel filter.

Maybe an ignition harness problem? i recently have replace one on an S-10 also check fuses too sometimes one is burnt out/ check computer? check injectors if getting spark?
