85 2.8 bronco 2 advanced timing issue

[timmtimm07]

Ok guys, I have a 1985 ford bronco 2 with the 2.8 manual with 4 wheel drive. I've been having problems getting advance in my timing and Ive already tried to replace both the ignition control module and the engine control computer and neither fixed the problem. I was told that i was gonna have to replace the whole wiring harness, just thought I'd get another opinion before i started on such a project. Any tips???

Have a read here:

The work sheet can be very helpful, even if you have gone over everything before.

Have you pulled the codes. All of the senxors have to be working correct or it will allways default to limp mode. If you dont need to pass emissions do the duraspark and dont spend any more money on the computer. The harness prtobably wont work either.

The harness is very doubtful; I've worked on a few of these and only once did I have to splice in a wire - never a whole harness.
First, follow the advice on pulling codes; then tell us what codes you have.

ALSO: I recommend a repair manual (like Haynes) on any car as a must to begin with.
