1986 2.9l starter relay wiring diagram

gruntgoo · Jan 13, 2009

Could anyone please send me or reply to this thread with a diagram of the correct relay wiring for a 1986 2.9l? Thank you. My issue is the truck will fire up with the key in the start position but as soon as you let go and the key goes into the run position, it shuts down. I've replaced the ignition switch, module, relay, starter, wires, and battery tracking down an unrelated issue, but now it won't stay running. :annoyed:

The problem isn't in your starting system. The starting system is working fine. You need a diagram for the ignition system. You have no ignition power.
Take a simple test light and check to see if you have power to the coil in the "on" position. If not the problem is between the ignition switch and the coil.
If you have power at the coil, you need the then test for power at the ignition module (TFI). If you have power at the coil but, not at the ignition module, the power loss is inbetween the two. I would start by looking at the wiring in the left front corner of the motor (behind the power steering pump).
