Psych0matt Posted September 17, 2007 Author Report Share Posted September 17, 2007 or you could buy one of the 4 that I have I thought of that, but I want it tomorrow or tuesday at the latest hopefully, so that this weekend is make it look nice, more than find the stupid problem Quote Link to comment Share on other sites More sharing options...
pwmin Posted September 17, 2007 Report Share Posted September 17, 2007 Hopefully it's the ICM and not a short somewhere in the harness. that was the next thing i was thinking on my 91 cuz the 96 engine swap wiring wasnt done too well (already spliced a bunch of wires that were just twisted and taped together ). hopefully, just the ecm will fix it.

Psych0matt Posted September 17, 2007 Author Report Share Posted September 17, 2007 well, none of the wiring looks tampered with, so lets hope that's a true statement Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted September 18, 2007 Author Report Share Posted September 18, 2007 ok, got the coils and ICM off, and the plate between the ICM and coils has lots of powdery corrosion against the back of the coils, as well as it looks like there's moisture in the greasy protectant layer stuff on the board: Â Â fronts of everything: Â and rear of everything: Quote Link to comment Share on other sites More sharing options...
slick Posted September 18, 2007 Report Share Posted September 18, 2007 That grease is fine, looks like white lithium grease. Nothing to worry about. Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted September 18, 2007 Author Report Share Posted September 18, 2007 That grease is fine, looks like white lithium grease. Nothing to worry about. Â oh no, I know that, i just meant it looks like moisture has been trapped between that and the plate for a while, and also behind the coils, causing the corrosion Quote Link to comment Share on other sites More sharing options...
slick Posted September 18, 2007 Report Share Posted September 18, 2007 Oh, gotcha. Put some di-electric grease in there then to prevent water from getting in. Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted September 18, 2007 Author Report Share Posted September 18, 2007 i will when I put it back together this weekend hopefully Quote Link to comment Share on other sites More sharing options...
5speedz34 Posted September 18, 2007 Report Share Posted September 18, 2007 I can't find the picture, but I don't think the plate is supposed to come off. Â I would replace all of that, w/good working ones. Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted September 18, 2007 Author Report Share Posted September 18, 2007 yeah, I bought an ICM from a member, so that should be here by weekend, and I'll see if Ken has some coilpacks, or if he can grab me some this weekend Quote Link to comment Share on other sites More sharing options...
5speedz34 Posted September 18, 2007 Report Share Posted September 18, 2007 Just be sure I would take the ICM and get it tested. Coils can't be tested, but hell for as easy as it is to pocket coils and ICM's I have hundreds! Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted September 20, 2007 Author Report Share Posted September 20, 2007 Plugged in the new ICM, and no blowing fuse!!! however, I don't want to throw these coilpacks back on without knowing their condition. Or if that would be safe to do for the ICM? Ken took a quick look and seemed to think they would be just ok, but I also don't want to buy 3 brand new ones. suggestions?

Psych0matt Posted September 20, 2007 Author Report Share Posted September 20, 2007 grr, stupid coilpacks!!! (i needed a break!) Quote Link to comment Share on other sites More sharing options...
pwmin Posted September 20, 2007 Report Share Posted September 20, 2007 grr, stupid coilpacks!!! (i needed a break!) i hear ya. i was about to give up on mine on tuesday Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted September 20, 2007 Author Report Share Posted September 20, 2007 ok, ICM and coilpacks back in, the fuses aren't blowing, but I still don't have spark... any thoughts? Quote Link to comment Share on other sites More sharing options...
ManicMechanic Posted September 20, 2007 Report Share Posted September 20, 2007 cps? check for injector firing...check wiring too. Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted September 20, 2007 Author Report Share Posted September 20, 2007 im thinking maybe CPS. would the injectors not firing cause the plugs to not fire? Quote Link to comment Share on other sites More sharing options...
Crazy K Posted September 20, 2007 Report Share Posted September 20, 2007 hmmmmmmmmm!!!!!!!!!!!!! Â Â I think it is time to pull the plenum and ohm the injectors! Quote Link to comment Share on other sites More sharing options...
ManicMechanic Posted September 20, 2007 Report Share Posted September 20, 2007 CPS, ICM and injectors are all tied together. Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted September 20, 2007 Author Report Share Posted September 20, 2007 ok, so at least I have eliminated the short Quote Link to comment Share on other sites More sharing options...
ManicMechanic Posted September 20, 2007 Report Share Posted September 20, 2007 Possibly...It's possible that the wires between the ICM and computer or ICM and CPS are bad and you just moved them around enough that they aren't touching each other or metal.

Psych0matt Posted September 20, 2007 Author Report Share Posted September 20, 2007 possible, but that would kind of surprise me a bit Quote Link to comment Share on other sites More sharing options...
ManicMechanic Posted September 20, 2007 Report Share Posted September 20, 2007 Surprised me when mine did...They looked fine until I finally fished them out and saw what was happening. But do this, it's easy and free...Grab a 194 bulb...Pull the connector out of the injector you can get to without pulling the plenum...Straighten the metal contacts on the bulb and stick it in the injector connector - harness side - and then crank it over...No light, no injector pulse.
