Check to see if there getting signal from the switch to the relay... on the relay terminals (4) there should be 1 constant power , 1 constant ground,1 signal wire from ignition switch with key in the on position (usually a ground signal) , and 1 feed wire to the pump.. make sure you have all the appropriate powers and grounds ..

2005 ranger 3.0 truck starts pump runs presser good pump stops no presser after a few minnits


If you are talking about the fuel pump, you have only a few cheap fixes before blaming the expensive fuel pump. The fuel pump relay can overheat and kick out. A new relay could fix this. Autozone.com offers free fusebox layouts and wiring diagrams just for registering your truck with them for free.

Sometimes the horn relay will interchange with other relays. Look at the part numbers and use the horn to test the fuel pump relay. Or switch the 2 relays.

A fuel filter could be clogged and overloading the fuel pump. Put in a new filter.

After that, its a case of testing the fuelpump leads and see if the fuelpump is shut down.

I hope my solution helps.

Wiring diagram


Then the fuel pump has failed most likely. It is electric of course and located inside the fuel tank, the fuel tank must be removed in most cases to replace the fuel pump, and don't forget to replace the fuel filter

NEED TO KNOW WHERE THE FUEL PUMP RELAY SWITCH IS FOR A 1998 CHEVY S10 TRUCK...


For the 1998 s10 theres no fuelpump switch, there is a fuelpump relay. the relay is in the engine compartment inside the fuse/relay box. the relay will be labeled on the inside cover of the fuse/relay box cover. besides the relay the only other problem for a fuelpump not working on these trucks is the fuelpump is bad or the wiring connector to the pump is bad.

We replaced a bad fuel pump on 06 escaped limited. There is no power to fuel pump. we have checked all fuses, relays and reset switch. Where else could the problem be?


Hello, You might try a Relay that controls the PCM or ECU. They would be in the Powerbox where the fuelpump Relay is. Some of the Relays are identical so you could buy 1 and it would be a backup part for several.

You should also look at the other things the Ignition switch turns on in the Run position. Does the radio work, the fan motor, or turn signals? If they do not work look at replacing your Ignition switch.

The PCM and ECU get their power indirectly from the Ignition switch. When all have power they will connect to the fuelpump Relay. Since you said you checked the Relays, I am taking that to mean you checked the fuelpump Relay only. Many times people do not know that there are several relays which all need to connect to get the fuelpump to run. When you determine the Ignition switch is good, then the ECU and PCM relays should be getting power. Have you tested the fuelpressure Regulator? It needs to demand fuel from the pump.

The fuelpump relay depends on the ECU or PCM relays to work. One of the 2 relays may be bad and preventing the fuelpump relay from working. When you get to trouble shooting the terminals you can get wiring diagrams online or the info may be in a book at the Autoparts store.

One of the benefits of using a Dealer with the hardest problems is the tools they have. They have machines with connectors that match every wiring connector inside your car. If one section is unplugged they can test the wire loom section by section until the problem is found.

I hope you have found my solution to be very helpful and that I have brought up a few new areas to try. If trying different parts does not help, you are left with a wire by wire battle to fix this and the Dealers' better tools may make more sense.

We have a 2004 Ford Escape that had the fuel pump replaced at 29,000 miles, 2 1/2 years ago. We just experienced the same problem and our mechanic again replaced the fuel pump. The mileage is now just...


Hello, I looked at the Reports for TSB's (Service Bulletins) for your vehicle and there are none for this problem. There are a few things that you can try to replace that are not expensive. The fuel filter and some Relays.

I would suspect that aside from using additives to the fuel, there can be only a few possible problems. The fuelpump is either running when it should not or there is a ground problem. For the running when it should not, there are Relays for the fuelpump and I believe a PCM Relay which can turn the fuelpump Relay on.

These Relays have more than 1 set of contacts in them, and 1 set may work fine and the other set may be sticking or failing to make contact. Sometimes it is a problem like yours, an underlying long term problem that causes a part to fail over and over. What I feel may be happening is your pump is not shutting off when it should or something is grounding through your fuelpump because of a bad Relay.

The Power side of your fuelpump has a fuse, the Ground side does not. If the Relays stick and allow a different device to ground through the fuelpump, that could be your problem. I would try a new fuel filter and a few new Relays. They are in the Powerbox under the hood and should be labeled. They would be handy as backups as many are identical. Just mark them for ID.

Gmc yukon turns but will not start dont hear the fuel pump on in the fuel tank


With ignition key on run, use test light to verify you have positive & ground to fuelpump. No power (positive) check fuelpump fuse. No ground check fuelpump relay. If both positive & ground fuelpump needs to be replaced.

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

I have replaced the fuel pump amongst a lot of other things. I can spray gas or starting fluid in the throtal body and it will run rough untill the fumes ware out. Its a 1995 ford explorer 4x4 xlt


If you hear the fuelpump operate the first 1 or 2 seconds when the key is turned to RUN position, the fuelpump is working. If you do not hear the fuelpump run, check the Inertia switch which should be in the side panel of the rear cargo area. If you have an owners manual check for the Inertia switch location.

To reset the Inertia switch, hold the button on it for 2-3 seconds. You should now hear the pump run. You may also have a fuelpump relay under the hood in one of the Powerboxes. The Powerbox may have a fusible link from the Battery. When the fusible link is OK and the Pump Relay is OK, there is a fuse in the Fuse panel. Then finally the Ignition switch will trip the Pump relay. As power flows through the wire to the fuelpump the Inertia switch can break the power connection.

So you have 5 powerpoints before the fuelpump will work. Fusible link, Pump Relay, Fuse Panel, Ignition Switch,and Inertia switch. These must all work before the fuelpump can run.
