I made some progress today.

The coil wanting to fire fixed itself. That sounds weird, but after bumping the engine over (screw driver across the starter relay terminals), it didn't do that again. Perhaps the distributor was in just the right position that the coil wanted to fire? Is that even possible?

I was able to get the truck running by having the key in run position, jumping the starter relay, and fogging starting fluid into the air cleaner.

I still have NO JOY on the IGN Start or IGN #2 circuits. I'm really thinking I've managed to get two bad ignition switches back to back.
