'86 F150 Relay Question
An older friend of mine is attempting to get an '86 F150 Lariat on the road after the previous owner allowed it to sit for 8 years. Wiring has been eaten away by rodents and it looks to be a nightmare dealing with the wiring issues.
The truck has a 302 engine with multi port fuel injection, automatic transmission, 2 wheel drive.
He wants to know if it has a fuel pump relay and an EEC relay.
Thanks for any help.

Yes it does. See the wiring diagram here (page 104) Electric Fuel Pump Control - ???Gary's Garagemahal
and here (page 60) Electronic Engine Control - ???Gary's Garagemahal
If fuel is 8 years old, your going to need to clean the entire fuel system (maybe drop the tank). Gas goes bad after a few months.

The link to the Electronic Fuel Pump control was a blank. I looked for it at his site, but was unable to locate it.

That's odd, I can click on the link and it works for me. Do you a popup blocker or something blocking the page?

The fuel pump relay should be on the front left firewall under the hood. It is almost directly under the hood hinge. The eec relay i think is right next to the eec under the dash on the right side of the steering column. Dont quote me on that though.
