OK, what's a V20?
You said you have had a problem. What fixed it before? Or did it get worse?
Was it raining? Or damp conditions? What about the plug going thru the
firewall?
How about brake lights? Flashers?

1988 Old Body trucks went from being C/K's to R/V's. V-20 would be a
4WD 3/4 Ton. R/V trucks go from 1988 to 1991.

I could see why he would want to keep it.
Thanks for the info.
Shame they do not make them like they used to.

Got it!! The fusible links were fine. Frustrated, I disconnected the
wires from the starter and pulled them out of the harness all the way
back to the fuseblock. The wire that feeds voltage to the fuseblock had
corroded so badly that it broke off. So, no starter signal, no fuel
pump, no fan, no radio.

Thanks everyone.

the battery, starter and ignition switch and it still won't start. What
am I overlooking? I didn't see any fuses in the fuse block that looked
like they were involved in starting. There is voltage to the headlights
but not to the dash when turning the key.

I would stop trying if I didn't love this old truck so much. Thanks in
advance.

Good job...

Well, it's not running just yet. After a couple days looking I found
the correct terminal end that would seat into that monster plug. Now,
I'm trying to clean all the light green powder from that location on the
fuse block where that plug connects. I called around about a new fuse
block but, the dealership doesn't have any info before 1992 and the
salvage yards I've been to don't have the years that would work. I'm
hoping that the block is something that I can take apart and replace
that terminal socket for a better connection.

Ok, I fixed the broken wire in the plug that brings power to the fuse
block as well as the connector within the fuse block that said wire
couples with. I finally have power to the starter switch but now it
goes dead when I turn the key to run or start. I do have power in acc.
It is a brand new switch and just to see, I tested the old switch with
the same result. I've been told it's probably the ACSU/ECU. Which
seems to make sense, electrical short kills ECU. What do you guys
think? Is there a way to test my ACSU?
