Fuel pump harness diagram needed?

Hi,

I attached a few pics below. The highlighted wires are related to the fuel pump. I'll try my best to explain how it works.

First, there are two fuses. When the ignition key is in the start or the run position, then fuse 23 gets power. The power from that fuse goes to the primary side of the relay. For the relay to react, a ground path is provided by the powertrain control module (PCM).

When this happens, power runs through the primary side of the relay and it becomes an electromagnet. At that point, there is a switch in the relay that is magnetically drawn closed, and power runs from fuse 8 through the relay to the fuel pump motor.

Here is a link I feel you may find of interest; it explains how a relay works and how to check one:

Let me know if this helps or if you have other questions.

Take care,

Joe

See pics below. The red arrows I drew show the direction the wire is going.
