First check the fuel filter. check before and after the filter if you get fuel before it then check after it, no fuel before go back to the pump. if you get fuel after then go to the fuel rail on the motor. open the line before the pressure regulator, if you get fuel then check after the regulator, if none after then the regulator is bad, if the regulator is vacuum assisted check your vacuum.

SOURCE: How do i check the fuel pump on a 1998 Pontiac Grand Am?

The easiest way to check if the fuel pump is working is to listen for a whirring noise when you turn on the ignition switch. No noise means it is not working.Check the relay a suggested.If you do hear a whirrring noise check the fuel filter. It is located under the car at the end of the tank.

SOURCE: fuel pump location 2001 pontiac grand am

The fuel pump is in the fuel tank.Sit in the car.....turn on the ignition switch to run.....listen very closely to the rear of the car...or have someone kneel down by the back wheel.....you should hear a "prime cycle"......the pump running for 2 or 3 seconds if the key was off for 15 seconds before trying this.If you hear silence you most likely need a fuel pump.Before pulling the tank down....check for power on the gray wire at the fuel tank connector just ahead of the rear axle under the car.Check for power with a test light that will last for 2 to 3 seconds as you turn on the key to run.Power means you really most likely need a pump.No power means you may need a fuse or a fuel pump relay.

SOURCE: Fuel pump on 2004 pontiac grand am does not come

Well i would change the fuel filter first. Then if that doesn't fix it there might be a reset button on the inside of the trunk for the fuel pump actually look for the reset button first. If you don't have one there is a relay switch under the hood sometimes they fail. You have three Ac,Fuel pump, door locks. The way i do it is turn the key on have some one put there hands and feel for the switch to work when you engage the power locks mark it with white tire crayon and feel for the ac when you turn it on it will still click even with the engine not running. mark that one also, Now the last one has to be the fuel pump relay turn the key on and it should click. if no click is heard? You have a bad fuel relay switch. replace it. If you feel the click and hear it? That would mean the fuel pump is bad. And these are in the tank. But please go with the easy stuff first. it might seam a waste of time checking the relays and marking them but i always fo this and mark them. cause you never know when your gonna need to find the relay something.
Good luck!
Hope i helped.

Check for spark (pull a spark plug and arc it to a grounded surface) and check for fuel to the engine (can be done through the spark plug hole opened by removing the spark plug)

2004 grand am stuttered then stopped working all together, wont start at all


Fuel pump? When you turn key to ON, do you hear the pump come on for 2 seconds to pressurize the lines? If not, you will need to have the fuel pump circuit checked for a failed fuel pump.

If the pump is working, start looking into the ignition system by checking for spark on one of the spark plug wires. If no spark, possibly the ignition control module or the crank position sensor.

2000 Jeep Grand cherokee Laredo wont start. Engine turn over . No noise from fuel pump with ignition on. Replaced fuel pump and filter.Turn ignition on- pump did not run.Jumped the fuel pump at the pump...


sounds alot the the pcm it controls the fuel pump and ign system but the anti theft would keep it from starting because the key has a transponder in it programmed for that vehicle and that would kill all ign if triggered

2000 Grand Voyager blowing the ignition fuse


Was the old fuel pump bad? It might be worth the cost to replace the ignition switch. The wires to the fuel pump would be a second guess if the old pump was bad and burnt the wires before the fuse went. When you eliminated the fuel pump you also eliminated the wires to the pump and it started. Then you replaced the pump, but not the wires. The ignition switch is the other end of the circuit.
