SignUp Now!save that part the only relationship it has to your problem is its 2 feet from the ignition moduleTook some offline advice and changed the crank sensor.
Make sure to take it for a long drive. The pcm in mine always failed after the car was driven 20-30 miles. Hopefully your issue has been resolved.Rebuilt Delco pcm from rock auto is in, problem solved!
No idea how that was possible, never hit bad pcm on the tree with any parts. But hey, now I have a few "known working" parts laying around
I let it run for 10 minutes or so with no codes, we'll see how it runs when I have the time to take it out for a spin.
Thanks for the help everyone, this forum is great.
Update, alternator figured itself out, we're good there, but still displays excessive retard degrees even tho functioning knock gauge shows nothing, any ideas where to start now? Also after reaching "yes" I cleared code again, this is probably no the proper procedure? If incorrect and after I get code to set, I then get to move to yes since code 42 is still displayed on scan master and brick scanner.Well this is as far as I got and boy did I make this thing mad when clearing the codes,no other codes present, seemed to have misplaced my turbo tweak code list sheet, but now it appears alternator not charging and my knock is through the roof
As much as I hate to say it, im willing to bet it's something I did installing scanmaster, in the freezing cold in a fellow turbo Buick members driveway. And even if so I'm not ashamed to admit a screw up and if it's something I did I'll still adviseUnfortunately, this is 37 year old wiring. Oddities will at best, be minimal. I had a 1964 Pontiac with break in the harness I had to send out 30 years ago, I would have never found it.
