Every time you open your drivers door you hear a buzzing sound under the car. That sound is from a working fuel pump priming fuel before you even enter the bus, anticipating a system start up. If you don't here it then it must have seized. More often it happens during early morning or when it sat for quite some time. You can also operate the fuel pump manually by using a jumper wire to the relay. The relay number could be 67, 80 or 167. I wouldn't recommend this if you have minimal experience working on fuel systems, it's very dangerous. It will spark if done incorrectly and set off a fire.

How do I diagnose and replace the fuel pump?

What kind of car is it?

First you need to find out if the car is lacking fuel or spark?

Pull a sparkplug wire and see if it sparks while cranking the engine. Hold the wire near the engine and see if it sparks to the engine. if its a deep connector put a screw driver in it and hold that near (1/2") the block or any grounded metal part. If there is no spark then that\'s your problem and you must find out why. To check for lack of fuel open the air intake hose, between the air cleaner and the engine intake carefully squirt a little fuel in and crank the engine.. If the engine tries to run, fires, then you are missing fuel. in almost all late model cars that are fuel injected the pump is in the tank.. on most American and Japanese cars you must remove the tank to replace the pump. on many German cars you can get to the pump or pumps under the back seat. There is a relay that drives the pump. when you turn on the key you shoud hear a click followed by another click 1.5-3 seconds apart. Many time you can hear the pump run for this short time. Open the cas cap and listen for the pump running. These pumps are expensive and many times hard to replace. Make sure the pump is bad before you go to replace. And last.. Possibly first.. Remove the fuel filter blow through it and make sure its clear. Since you have it off replace it. Good Luck.

Fuel pump needs to be replaces on 2000 Chevrolet suburban, do I also need a new filter, relay and induction?

Do you know for sure that the fuel pump failed or do you have a bad relay? If the fuel pump relay is good no you don't need to replace it. The fuel pump unit comes with the sending unit and a sock filter. I would replace the inline fuel filter when you replace the pump. In line fuel filters need to be replaced every 36000 miles. If that filter starts to plug up it makes the pump work harder which leads to premature failure.

Fuel pump went bad need replacing what is the quicks way to do this

if the pump is in the tank, (i think it is) remove fuel from tank. If you have never replaced fuel pump before it is easier with two people. Also buy a complete fuel pump

I think the fuel pump is not working, do I have to drop the gas tank to replace?

Yes the fuel tank has to come out to replace the fuel pump.Easier if tank is 1/4 tank or lower.Before doing this make sure that your getting power to the fuel pump.If not check the fuses and the connector for the fuel pump.You can check for power with a test light.It will be the gray wire.Light should come on when the key is turned on.Will only stay on for 2 or 3 seconds unless you crank it.Hope this helps.Good luck.

95 isuzu rodeo. 6 cylinder. hesitates, poor fuel mileage. previous owner replaced coil packs but not sure if put plug wires back on right. switching around doeasn't better or worsen problem.. got the...

I would start with getting the right firing order you can look up the spec online at autzone on there site they always have diagrams than start by checking and making sure that your getting fuel either a clogged fuel filter or a bad fuel pump that is starting to go bad. Make sure you only have 1 fuel pump some cars have 2 if you have to chances are the one inside the gas tank is the one that 99% of time goes bad but check both for fuel coming out of them to be sure. To me it sounds like your ignition componenets need to be checked and make sure your confident on your firing order than start diagnosing .

What's the difference between fuel pump & replacement fuel pump

I dont think you have a fuel pump problem, It sounds to me like you have an alternator problem. You see when your alternator quits working the car will run on your battery juice untill it is out of juice and all electrical will go out when you put a new battery on it it will start working again untill the new battery is out of juice or untill the alternator is replaced. If the vehicle wont run then the fuel pump might have went bad too. I hope that helps you out.
