SOURCE: i have a 2000 jimmy with short in ignition system how do u correct

These vehicles come standard with passlock antitheft security. This has to do with your key and ignition. If its failing, the truck will start for 1- 5 seconds and then stall. If this sounds like your problem, go to this link.

08 nissan titan i have no power to fuses that. Go to injectors or coils or fuel pump

Disconnect the fuel pump, replace the blown fuse in the underhood fuse and relay center and see if the components power up. A shorted fuel pump will cause this along with a shorted engine wiring harness.

I want to find the location of the fuel pump relay on a se ford escort 1998 wagon.

Fuel pump relays are typically located in the power distribution box under the hood or mounted on the Drivers side fender wall. The Fuel pump relay, AC relay and Starter Relay are all the same type and interchangeable so you can change them out between each other, like move the AC relay to the Fuel pump relay position and see if that resolves the problem.

Will a 2008 yukon run with a missing fuel pump relay

{: ) Yes, if the vehicle is equipped with a Fuel Pump Flow Control Module (FPCM). The FPCM is located underneath the vehicle, left side chassis, near the Electronic Brake Control Module. Sometimes, when you check fuse and relays at the underhood fuseblock, you can still see labels and alloted space for the fuel pump fuse and relay. But the circuit is actually internally omitted or modified inside the fuseblock if the vehicle is using FPCM. An FPCM controlled fuel systems doesn't have fuel pump relay at the fuseblock, and instead you may find a FSCM fuse 20amp which gives battery power to the FPCM.

Where is the fuse for the fuel pump

There's a relay and a fuse both but if the fuse is blown the pump might be bad as if the fuse is'nt bad the fuel pump probly is. The circuit opening relay is behind the glove box it's powered by the EFI relay in the underhood fuse box and the fuse is the EFI fuse in the underhood fuse relay box
