No fuel getting to motor so no start. replaced pump fuses and relays all good. there is spark


you will need to check the plug to the pump on top of the tank. check for voltage. then if no volts trace the wires back. also you should check the relay have some one at the relay listening to see if it clicks when you turn the key. no click no volts no volts may be a warn out relay, if it buzzes change it.

2000 2.2l cavalier no power at the fuel pump


No, there would not be another fuse. How did you jump the pump, at the pump relay, or at the gas tank? I would want to know if the power feed for the pump is present at the relay. If you jumped it there, the feed is good. If you pull the relay out, one terminal for the relay should be hot at all times. Two terminals should be hot when cranking the engine over- the power feed for pump, and the signal from computer to the relay's coil side. If you have both signals, check for a pump ground problem.
If a security light is on, the pump or injector circuit may be immobilized.

How do you know fuel pump is bad, is there anyway it can be checked?


Well you use a fuel pressure gauge to check pressure at the injector rail, and you can check for power and ground at the gas tank to make sure the pump is running.

I have a 2000 hyundai elantra and it wont start not getting gas cant hear the fuel pump to i thought id look for the inertia switch but have not manual and dont know where it is can you help?


Hello Jeanette: My name is Roger and I will help you. Your car does not have an inertia switch that can be reset. Check the fuses and also make sure the fuel pump relay works.The relay is located in the passenger compartment relay box. Should say relay box on the cover. If all are in working order you will need to test the fuel pump itself.You do not need to remove the fuel tank to do this. Remove the rear seat lower cousion from the car. Remove the inspection cover to gain access to the pump. Unplug the harness and check for voltage when the key is turned on. SHould you have power at the pump plug ? the most likely problem is the fuel pump. Should you need further help please just ask. Please rate the answere. Thank You for using Fix Ya. Roger

Im having fuel pump issues. could you please tell me where the fuel pump is located on a 2002 Pontiac Grand Am SE


The fuelpump is located inside the gas tank, you will need to drop the tank to replace the pump, heres a picture of the pump and in goes in through the top of the tank, the fuelpump is called a fuelpump module because it comes complete with holder sending unit and all other parts as you will see in the picture,hope this helps, good luck.johnjohn2_17.jpg

Hi

Make sure to check the fuses, most of the time when this pump goes bad it blows the fuse, and fuses sometimes get corioded and dont make a connection take a look at the fuse box.
Fuel pump is located In fuel tank .Also fuel pump relay s located in front of batteryi

No power going the fuel pump on 1991 honda accord what should i do


If you have verified a no power condition by pulling the tank and measuring the power signal to the pump then either your fuel pump relay is bad, or you have a bad fuse, or a broken wire somewhere in between.

My guess is that the fuel pump no longer comes on when you turn the key to the on position and that you havent dropped the tank to inspect the pump yes? If this is so you may have a bad fuel pump as well. What I would do is check the fuses for the fuel pump and make sure they are not blown. Then I would check out the relay, visually inspect it, the top should come off of it, look for any burnt wire traces and components inside the relay, you may be surprised to find other relays in your car are the same as the fuel pump relay. Swap one of those out with the fuel pump relay and see if that fixes the problem, this will save you the money of buying a new relay before you know it is your problem. If the relay appears good then you may have to drop the tank and install a new pump. Some vehicles have harnesses under the hood which allow you to feed power directly to the fuel pump so you can test it to make sure it is good before you drop the tank. Some don't. You can feed power directly to the fuel pump by jumping the pins on the relay, I am not familiar with the pinout on your cars relay however and could not advise you which pins to jump to feed power directly to the pump. Get a chiltens or haynes manual, they should have wiring diagrams in them.

How do you check voltage on the fuel pump on a 2001 Chevy Silverado, was driving engine stalled but regained power drove three more miles and it quit running, I have spark but no fuel. Trying to check out...


Hello Dennis.
When you are checking fuel pump voltage on your pickup when you turn on the key the voltage is only applied to the pump for a couple of seconds unless you go to cranking position.
There are 4 wires leading to the fuel pump on your truck. The gray wire is the 12 volt positive power feed to the fuel pump and the black provides the ground. The orange and purple wires are your fuel gauge wires.
The relay for the fuel pump is in your under hood fuse panel and I believe is marked on the underside of the fuse panel cover. It should click on and off again quickly when you turn the key to "on". Having a helper to cycle the key would be handy while you put your finger on the relay and listen to it. Just because it clicks still doesn't mean it's functional but relay failure on these models is somewhat rare.
I would start by checking for power at the fuel pump harness.
Fuel pump issues are quite common on these model year trucks.
Hope this helps you out.
