Received a Q about ICU that I can't answer, maybe you can help? 1989

Following is the email I received. I hope someone has the knowledge to help him, I do not.

i went to the bone yard today picked up a couple of ignition modules /
both are older than my 88, but i decided to try them first, both work
well, but i could not get my original icu/icm to work, decided to
disconnect the battery to see if a computer reset was in order in order
to work, still nothing, why would my original moduel quit???? really
pissed at myself knowing the 88 is supposed to be the best and that i
may have destroyed it.

any idea what may be going on?

p.s. made sure ignition was off during changeouts

part that was in my 88 = 1537308 / part thats in it now 3517641 / the
other one i bought is 1346107 out of an 87

was thinking of pulling the covers off to chk the connectors solder
joints to the p.c. board.

with the original module it just cranks no fire

It is my policy to allow my email address in my profile, there are some things that should go that route.

As to technical questions, however, I prefer that the questions come on the Brickboard. That way others having a similar situation can learn, and others with more and better knowledge and writing ability than I can render assistance. Sending direct to me does not get a faster answer. I'm slow everywhere.

    the 3517641 is still running fine in my 88 i have also noticed that it starts quicker and the kick down seems to engage sooner with this module. now that said i dont know if my original was on the edge of failure before i went to the bone yard and i pushed it over the edge when i reconnected it, or if i altered something in the cars computer by putting a different icu/icm in,, both my backups work for now, and need to find some metelyne cloride to remove the potting compound from the 1537308 it looks like a capicitor may have gotten hot as the potting on top of it is cracked(may just be age) and the connectors interface with the p.c. board looks fine, no cold solder joints that i can see.

          depends i guess somewhat on what your personality is like. they refer to me as eeyore,, dont know if they think im a depressed ass some people here think of me as an ass too, but none the less, 700 is a little siplistic, now 007 that would be a good one. once i was thinking of using earwax as a handle but oh crud suits me fine for now. think i picked it up in the post divorce phase of my life, which is still pretty much now.
