Need to know where to locate the fuel pump harness for 91 ford escort lx?

Answer 1

The term "harness" refers to the wiring loom. The fuel pump harness would be the wiring to the fuel pump assembly. That wiring would be part of a much greater wiring loom, that would run along the frame rail, and immerge under the hood to become part of the main engine control wiring harness assembly, which includes all the wiring to all the engine sensors and solenoids, and even runs to the computer. You can locate one end of the harness where the connector plugs into the fuel pump on top of the fuel tank. It will go from there, and pretty much run the length of the car, spidering out under the hood, and going just about everywhere. There may be a connector or connectors that separate the rear body and fuel pump harness from the rest of the vehicle harnesses, but don't count on it.
