There was a what I think was a resistor in the wires running to the coil on my 1987 f-150 it has a 302 in it and it got cut off and now I have no clue how all the wires go back on the coil and every way I try the wires the truck will get hot an die, after it dies it has no spark coming from the coil but it has fire going into it. Then about 30 to 45 minutes later the truck will start and run fine but it has a miss.I had the ignition module tested and its good, ive tried 3 different coils and it done the same thing so I know its not the coil. But I cant under stand the wiring diagram in my book. Does my truck have a crank sensor? Can any one help me?

No crank shaft sensor.

But you should check your pick up coil in the distributor, and make sure no wires are grounding out.

These tests are for the Dura spark ignition it has a module with two connectors a four wire and a two wire, if you have the thick film ignition that screws on the side of the distributor these are not the right tests...inform us and we will supply tests for that!
