No fuel my 91 sidekick was shut off in the garage, never start again, no fuel, is there some kind of relay that runs the fuelpump? all fuses and fusable links are good, when I run power to the pump wires, it pumps, take direct power off, no fuel, someone help!!

Check fuse or relay to fuel pump. Obviously not getting power. Start at fuse blocks under the dash or under the hood!

Check that the fuel pump is not jammed , eventually replace it, check also the fuel filter.

There is a box under the hood next to the battery with fuses and relays.
there is a fuel pump relay and or Auto shut down relay that could be bad.
It shuts down the entire system ignition and or fuel pump.
ASD Relay.

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.

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.

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.

The fuelpump is primed by the oil pressure switch.When the fuel pressure reaches normal PSI the computer shuts that pressure switch off and turns thepoweron to the fuelpump relay.You have a bad fuel pump relay

Hi,welcome to fix ya. this could be caused by the main (PGMFI) relay under the dash it controlls the fuelpump . There is a circuit board inside it that cracks and causes the fuel pump to shut off,

Check for power at the fuel pump, I've seen these have a bad connection for the fuel pump in a connector behind the left rear taillight. If that connection is good and you have power and ground to the pump when you cycle the key or crank the engine, then replace the pump.

Fill the fuel maybe?
