Your guess is as good as mine. But a solder joint in this area is the only thing that makes sense to me from what is happening. I would say the crystal.
I would get a computer from a salvage yard out of a salvage yard and see what the fuel pumps do as was pointed out above.

if I could find a computer at a salvage yard I would have bought one months ago. I can't find one at a salvage yard, I can't find one online at all...rebuilding/repairing this one appears to be my only option.

For testing purposes pretty much any computer (PCM) would work.
I believe the existing computer you have is designed with California emissions that's why it is hard to find. If you do not need to pass Cali. emission a Federal emission version will work.
I also found this one listed for a 1991/1992 F150 w/4.9L/Manual Trans/Cali. emissions: F2TF-AUB
