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.

Most all cars the fuel pump is in the gas tank and can be heard to come on when turning on the key without cranking the motor. some pumps you may have to put your ear right against the tank to hear it run. Yes it can run and not put out enough pressure to run the engine. The most common cause of fuel pump failure is fuel filter not servived every year on older cars most of the newest ones the only filter is in the tank on the pump as the repair has caused more problems with fires and leaks than the service is worth , You are likly to have to change the whole pump unit on that car fuel gauge sending unit and all one peice. Shopping for the parts the discount parts stores have good prices but the pro mechanics find their failure rate high and they won't install them as they don't want to do the job for free later. The fuel pumprelay is located in the underhood relay cennter and the lid is marked on GM cars Fords you have them numbered and sometimes the oners manuall wiitell hich one it is. With the relay removed and the key on there shoulbe two posts hot with a test light one with the key off. with the test light hooked to the positive one post will be ground ( the pump if its still good and another will turn to ground with the key just been turned on or cranking) Taking fuel tanks out and draining gas disconnecting fuel lines call for the right tools and experience. Someone whos done it before on a car like yours to help you and your handy with tools and have jacks jack stands flairnut wrenches for the fue lines on the tank and fuek filter. and a strong desire to do it right in a safe work area with a helper. if not call around to the pro shops and make you best deal and they still may run into rusted out fuel lines rusted or contamineted fuel tanks or even find that some how something other than fuel is in the tank that needs to be thrown away or even the whole tank. Peaple have found sugar and other cars killers inthe tank that can go on to the fuel injectors fuel regulater and you may need the relay too. Running on empty all the time just getting some gas and running it down to out is very hard on fuel pumps. Peaple stealing your gas can break the pump and gauge holder and introduce dirt to the tank. Theives don't care about you so their sloppie and damageing to your car, even punching holes in the tank to take the fuel. As the price of fuel rises and more and more peaple are out of work, This will happen more and more. Professional installation and dianoses is likly to be the best way to get your car fixed to stay fixed. Cheap parts in this area are a roll of the dice, and anyone can get lucky. Most of the cheap ones that I have put in failed in less than a year. Many pumps even good ones only have a one year warrentee
