Wiring Problem

Lately I have been experiencing some wiring problems. When I turn the key nothing happens; the check engine light does not come on and the fuel pump does not cut on. So I started checking for wires that were grounded out. I found a wire that was grounded out when the key is in the on position. It is the wire that comes off of the starter solenoid (it is connected to the same side of the solenoid as the positive battery terminal connector). The wire has a fusible link in it and runs into a connector. From the connector it then runs through the firewall. Is anyone familar with where that wire goes?

What year is your truck? The early Broncos didn't come stock with a check engine light or an electric pump. Not to say they couldn't have been added.

It goes to through the ammeter and then to the ignition switch as a power supply. Is the fusible link burned up? Are you getting power to the igntion switch?

Jason, doesn't the hot side of the fuel pump relay run to the starter solenoid with a fuse link?

It is a possibility, depending on how it was rewired into the Bronco. If I remember correctly, there is a fusible link that feeds the power side of the fuel pump and the EEC relay in a factory EFI application. Good point, Mike.

Shawagy, is this wire part of the original Bronco wiring? Does it go through the firewall with the OE bulkhead plug? What color is the wire at the fuse link and where it goes into the firewall? Where are your EEC relay and fuel pump relay located?
