Check the #22 fuse... These are known to blow, mostly due to the heater element in the fuel bowl shorting out.

With having sat that long, a new fuel filter might not hurt.

Update: Well guys looks like a PCM is going to be installed. After ordering a new harness that goes to the IPR because it looked suspicious due to some missing rubber protection and some dirt found in it did not fix the problem, he yanked out the PCM and found water in it and the side of it was totally corroded. Hope this fixes it!!!!!!!

Thanks guys for all your input and help. Next update in 3 days!

PCM! He said somehow at sometime someone possibly sprayed with high pressure into the engine compartment and it got really wet. Bad enough so it was corroded on one side he said and had visible water!

But the PCM isn't in the engine compartment. It is fed electrically through the firewall and is located behind the parking brake kick panel. Just confused. Here is a pic.

OK...Cool Beans....I just bought some Dielectric grease to apply on my PCM and IDM connectors, to help keep that very such thing from happening.

I bought the largest cans of dielectric grease possible when I put my whole project back together.. Its worth it to go through and clean out every connector and regrease it. You dont have to do it all at once, but dont take a few years to do it either, LOL! You would be amazed at which ones get gummed up!

I am tracking....I see a lot of threads on various forums and as these trucks age along with harnesses and connector(s)....sometimes "wiggling" wires may help to find your problem....

On our trucks, the dielectric grease should be used on the weather pac seals , not on the contacts ...

pjwoolw- You're correct! He said "it's tucked up in behind the firewall" and it's pure speculation on his part as to how water got in there since we do not know, but that an "engine spray" seemed most likely. I haven't seen it yet so I'm just relaying our conversation to you all. BTW...Great diagram of the engine compartment.

And for what it's worth...he said he's finding that the 1996 model is a stand alone year on quite a few parts meaning that though the 1994.5-1997 years are generally grouped...the 1996 has specific parts made only for that truck.

GREAT information here guys!
