BenKey Posted August 8, 2004 Author Report Share Posted August 8, 2004 make sure to check the plug in at the neutral saftey switch.... Never unplugged it. Link to comment Share on other sites More sharing options...
BenKey Posted August 8, 2004 Author Report Share Posted August 8, 2004 Zippy, do you have access to ground locations? I have "some" schematics that show where everything ties to a ground, but more interested in the 3-4 of them that go from the engine to wherever. It does start and run, just something going on weird with power. The main thing is no gages - which I won't run the engine for too long at all when I don't even know if I have oil pressure.

zippy Posted August 9, 2004 Report Share Posted August 9, 2004 maybe this might help. (picture deleted) Link to comment Share on other sites More sharing options...
BenKey Posted August 9, 2004 Author Report Share Posted August 9, 2004 Thanks, Zippy. That does appear to be the one I need. Since all of those functions don't appear to be working normal. Can you send that file to me email to print off? Any more? Link to comment Share on other sites More sharing options...
smithl3 Posted August 9, 2004 Report Share Posted August 9, 2004 Ben, I wish you luck my man. Not to say you haven't checked it, but when I was getting my dyno tune in Syracuse, I had my PCM in and out several times, and when it was loosely tighened up to the ground, the cluster was in and our and I had all sorts of electrical problems. I'm sure at this point you checked it, but the PCM not being grounded caused havoc in my truck. Good Luck pal. Link to comment Share on other sites More sharing options...
BenKey Posted August 9, 2004 Author Report Share Posted August 9, 2004 I think my problems are figured out. It was misplacing one ground and not placing another. Thanks to Cody for the pics and Zippy for the schematics. Hopefully, after I get those fixed, my problems will be gone. Link to comment Share on other sites More sharing options...
TurbochargedBerserker Posted August 9, 2004 Report Share Posted August 9, 2004 Awesome Ben!! You know... Driving to Orlando would be a good way to break it in... Link to comment Share on other sites More sharing options...
BenKey Posted August 9, 2004 Author Report Share Posted August 9, 2004 Well, good news and bad news. Good news - got my grounding issues all worked out and the motor runs just fine. Got some tuning issues, but that's to be somewhat expected. Bad news - tranny issue. It needs to come out. Leaking fluid. Don't know when it will get done, not in any kind of hurry either. Could be this week, maybe next, or next. I just need a break. Link to comment Share on other sites More sharing options...
TurbochargedBerserker Posted August 9, 2004 Report Share Posted August 9, 2004 Hey Ben, My Grandfather spent part of his life as a mechanic, both for GM and as an independent. He taught me a few things about working on cars that I have found in valuable. First, your hammer is always too small. Get a bigger one. Second, a liberal application of Norweigan magic words lubricates any work you are doing on the car. Norweigian magic words? My favorite one starts with an 'F' and ends with 'uck'. Third, if rule two fails, see rule 1. Sorry to hear you're having more troubles!! Link to comment Share on other sites More sharing options...
BenKey Posted August 9, 2004 Author Report Share Posted August 9, 2004 Well, scratch the bad news. Everything is fine now. Truck runs good. Just need to work out some tuning issues. Link to comment Share on other sites More sharing options...
