Hi. I have not been on in... almost 5 years? Wow... Anyway... I am looking at a '91 F150 Std Cab 8' bed with a 302. The guy thought it may need a timing chain, because it is difficult to start. It may be unrelated, but it may be the problem, but I glanced under the upper intake manifold and noticed a broken harness. It looked like it has 2 wires, either red and white or orange and white (sorry bad eyes). It is toward the front, I could not tell what it went to. What is it/Could it cause the cranking issue? I did a search and did not find anything, maybe my search terms are bad.
