On my 84 F-150 im having trouble with it not firing.
It will crank up fine run fine for hours then all of the sudden it will stop firin.
Things ive replaced since it started acting up:
1. Ignition control module

2. Coil

3. Distrib cap and rotor

4. ignition switch mounted to the steering column

Ive checked all my grounds all the wires everything works fine sometimes.
The only time it will fire when it does quit is when you stop spinning the engine over then it will hit.
I havent changed the pick up in the distrib but i do have it.

Does any one have any thoughts that might could get my rolling for good?

I would say coil, but you already said that. Next, I would say module. Put the new module in and try it.

I suspect that something is breaking down due to heat. That usually means that it is something electronic that is "potted".

Sounds like the only thing left is the pickup module

Change the radiator cap.

1) Remove existing radiator cap. Hold it in position above the radiator.

2) Back the vehicle out from under the radiator cap's position.

3) Pull a newer, more reliable vehicle into the above mentioned position.

4) Put radiator cap on newer, more reliable vehicle.

5) Done.

Now thats funny right there.
