Yet another fail to add to the saga: the MSD coil is now dead.

I got the new ignition module today, installed it and the truck started immediately. I let it run for a bit before trying to drive it, because I know how this turd is, and sure enough it died after about 10 minutes. Tried again, it lasted for 2 minutes before dying again.

I borrowed a multimeter (mine's missing again), started measuring everything. The primary resistance should be 0.7 ohms, and there's zero continuity between the positive and negative posts of the coil. The secondary resistance is supposed to be 4.7k ohms, I got 5.68k.

I'm considering switching to an internally resisted coil. Haven't decided yet.
