just looking for any more insight......
 
*** update*** well yeah
 
looks like 4 out of those 5 modules I had were BAD!!!!!! only ONE after 10 tests still held up...
 
it was one of the junkyard ones.... the new one from autozone the previous owner put in was junk.. the original was junk... and 2 of the 3 i grabbed from the yard were junk... so now I have a KNOWN working icm and a good vcm(i think) we'll slap it back together tomorrow and get this thing hopefully concluded....

ok well icm tested from advanced auto parts.... check
vcm from 95 jimmy slt automatic 4x4.... check
new ignition coil from auto zone... check


it started... and ran .....


old coil reistance

primary -primary.......0.3ohms
each primary to secondary....8.8 ohms.....
each spot to metal body.... ofl

NEW coil resistance
primary-primary......0.6 ohms
each primary to secondary....8.9 ohms....
each spot to metal body.... ofl

anyone else see this as odd.... NO idea why it worked but it did.. I'll post in a week or so and follow up....
 
 
well it ran till it hit the first few bumps... the issue became more prevalent..
 
I got it back to the house.. and got it running again.. i wiggled the harness on the driver side... it died...  5 times in a row....so WIRING it is.. I FINALLY bit the bullet and ripped out the harness...

yeah after 5.5 hrs rippingout the harness ( that trans to engine bolt holding the clip is in THE most retarded spot....) it was a splice on circuit#9 the fuel pump oil pressure sensor relay.. it was completely rotted away.. so I spliced it back.... soldiered... silicone... heat shrink...  and I also found the ground terminal to the vcm was mangled... so I cut and put on a new ring terminal... then went thru the whole harness... and soldiered every splice ,.. then siliconed and electrical taped them... ( this WILL not happen again)... then I took my time got everythign back together .. I also added a new #8 ground from each ground point on the heads... straight back to the battery... I will upload pix when I get back home.. dsl is too slow...
 
started up first try...  and I went back under the hood wiggled every harness like a mad man... not a single sputter.. I think I finally have this one fixed....
 
thanx for the help kyle....
 
tho I knwo this wont be a common problem for everyones truck.. if you're finding an electrical issue and have tried everythin else.... you may have to bite the bullet and rip apart your harness......
 
and or the record i DID have to rip out the whole harness.. not only to get the the problem...( right at the "y" of the harness) but to make SURE this wont happen again and fix everythign while its out....
 
thanks again
 
now onto more important things.. like ball joints...lol and winshield washer..( failed inspection for those...) DOH!!!!

I'm definitely glad you got it fixed Will!  Good job!  Wiring is not a fun thing for anyone and your persistence definitely paid off.
