Fuel pump not getting power. Wiring experts needed

isnt there i fuelpump relay under the driver seat? also the enertia switch resets the fuel pump(i think) which is in the trunk behind the driver side taillight. i doubt i did any help but hey, im no wiring/fuelpump expert.

The fuse links are all in the harness up near the starter solenoid. You are going to get to unwrap the harness starting from there unless someone else has an exact location to look. The fuse link is connected to an Orange/LT Blue wire. The other side of the fuse link is connected to a black wire that connects to a 10 gauge yellow wire that runs to the battery side of the starter solenoid. Start at the 10 gauge yellow wire on the starter solenoid and unwrap the harness until you find the fuse link.

If you can't find the fuse link, a 14 gauge wire with a 15 amp fuse could be run from the battery side of the starter solenoid to the Orange/LT Blue wire on the fuel pump relay.

Here's some help in understading how the fuel pump electrical circuitry works...

The electrical circuit for the fuel pump has two paths, a control path and a power path.

The control path consists of the inertia switch, the computer, and the fuel pump relay coil. It turns the fuel pump relay on or off under computer control. The switched power (red wire) from the ECC relay goes to the inertia switch (red wire) then from the inertia switch to the relay coil and then from the relay coil to the computer (green wire). The computer provides the ground path to complete the circuit. This ground causes the relay coil to energize and close the contacts for the power path. Keep in mind that you can have voltage to all the right places, but the computer must provide a ground. If there is no ground, the relay will not close the power contacts.

The power path picks up from a fuse link near the starter relay. Fuse links are like fuses, except they are pieces of wire and are made right into the wiring harness. The feed wire from the fuse link (orange/light blue wire) goes to the fuel pump relay contacts. When the contacts close because the relay energizes, the power flows through the contacts to the fuel pump (light pink/black wire). The fuel pump has a black wire that supplies the ground to complete the circuit.

With all the informative things you post in everyone elses threads I thought you knew everything good luck

Did you check the inertia switch?

To check the fusable links, check for voltage, test light or meter will work.
