Are you testing for power and ground at the pump?

    if you're not getting power at the pump then check the plug on top of the fuel pump/sending unit housing. if still no power then try to trace the wires (as much as possible) back to the fuse box looking for broke, chewed, or rubbing wires that may have lost power. also check all the fuses sometimes bigger fuses control smaller fuses, check for two power supplies to the relay - one for the electro magnet in the relay and one for the power supply to the pump. usually terminal 30 (in the fuse box) is the power supply to the pump and should have power all the time even with the key off. when energized the relay pulls terminals 30 and 87 together, 87 goes to the fuel pump from the relay. 85 and 86 are for the magnetic coil that pulls the other contacts together, one positive (key on) one negative (to computer). if you jump terminals 87 & 30 with a small piece of wire and get power to the pump then you know the wiring is good to the pump. check this and if no luck let me know i'll check back later.

SOURCE: 1996 CADILLAC DEVILLE, NO POWER TO FUEL PUMP

Check for a burned fusible link under the hood. If you have power at the fuel pump relay, you could have a bad ignition switch or bad oil pressure switch...accordianman

SOURCE: toyota camry 95' fuel pump won't turn on

I would definately check the fuel pump relay, should be located in power distribution box in your vehicle, you may be able to switch it out with a relay of the same type to see if it turns on the fuel pump, but you may need a new fuel pump if this doesn't fix it. Hope this helps.

SOURCE: my fuel pump is not getting power, I've changed

The fuel relay and inertia switch could be two different items. The inertia switch kills power to the pump. If there is a relay in between the inertia switch and the pump, then it would mean the inertia switch was tripped by slamming a door or an impact. Check your owners manual for the inertia switch.

No power at fuel pump


Sounds frustrating. Presumably you've also checked the fuse panel for blown fuses? Check to be sure you're at least getting power to the fuse, that will at least narrow down a problem before the fuse or after.

The oil pressure sending unit could be bad. If your oil pressure gets below 7psi than it shuts off all power going to the fuel pump. It is screwed into the engine block just to the right of the distributor.

My 2000 monte carlo will not start


You probably have a blown fusible link (between the starter cable post and the fuel pump relay), or a blown relay fuse or a bad relay. The fusible link and relay should have power always and can be checked with a 12 volt test light.

My 97 monte carlo will turn over but there isn't any power to fuel pump I know it works and I've changed all the fuses and relays and also got the key checked.... I don't get it also checked...


The ECM BAT fuse powers the fuel pump through the relay. If the gray wire has power and the black wire has ground, and the fuel pump does not operate, its bad.

Theres a few more checks But i'm sure you checked the fuel pump fuse already ..Use a test light and check to see if the fuel pump relay is getting power from the supply and from the Ignition feed. should be a schematic on the underside of the relay..if no power from the feeds check for a blown or rotted fuseable link or a maxi fuse..good luck

1994 buick park avenue . driving home and shut off


how did you jump the fuel pump relay, by bypassing the relay or by applying power to contact that closes the relay? If you bypassed the relay completely you need to b ench test the relay you can do this easily by using any 12v dc power source. If you tested the fuel pump relay by applying power to the relay and the pump run and developed pressure. I suspect a wiring or ground issue. Good luck
