No power to fuelpump or coil or coil driver so I ran a jumper wire and fuelpump and all started working what is causing no power


The common component to the coil and fuel pump is the ASD relay. The ASD (auto shutdown relay) is activated from the (ECM) engine control module by the ignition key, but in the event of a roll over or crash the ASD relay kills power to the engine and fuel.

Car cuts out after 15 mins run wont restart untill 45 mns later


Sounds like a part is heating up and failing. You can borrow a fuel pressure gauge from any Autoparts store with a tool loaner program. But you need to catch the problem as it happens. What I am getting at is if your lose fuelpump pressure and then the pump cools down and works again, you will briefly have low or zero pressure.

An electrical problem this closely resembles is a bad coil. Bad coils act this way. They lose power, cool down, and then work again. One thing would be to open the hood of your car when it fails. Leave the hood open and try starting after 15, 30, minute intervals. If cooling helps, then change the coil.

Another item is a Relay. Pretty much the same response as a coil, and an open hood would help too. Could be a Igntion Relay or Fuel pump Relay.

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.

I do not get any electric power on the feul pump, i have tried to activate the emergency shut off valve but still no power. i have taken electrical messurment at the switch but there was no power either.


Hello, You should have a fuelpump Relay in the Powerbox under the hood. The power goes through this Relay, then it has a fuse in the fusebox inside the car, and the Inertia sensor is next and then the fuelpump. If you have no power going to the Inertia switch, then you may have a bad fuse or a bad Relay.

Check with Autozone, Oreillys, or Advance autoparts for the correct Relay. Ford uses the same part for several jobs and you need to replace the bad Relay. Sometimes you can just switch identical Relays to find the bad one. Autozone is pretty good for having diagrams. A bad fuse would mean something went bad either on the Relay side or the fuelpump side of the fuse.

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.

Why wont my car start after replacing the fuel pump


Do you hear the fuelpump running? Check the Inertia switch under the right front passengers kickpanel. There is a button to press and it will reset.

This is a safety switch for impacts and when the fuelpump was disconnected, it can sometimes trip.

Also, when you diagnosed a bad fuelpump, there are Relays and fuses which supply the power. Your original problem could have been a bad relay.

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.
