Where can I get a tester PCM?

[RazzyB]

Still having problems starting when the interior of the truck is warm as described ad nauseum in my other post. Tried replacing the CPS yet again to see if I could get a signal on the tach when cranking, still no reading.

I either have an intermittent, heat-exacerbated short, or (as Daryl has repeatedly theorized) a bum PCM.

So...to test the second theory I want to know if anyone has a spare PCM I could swap into my truck to see if I can get the tach moving while cranking.

The code is NVK4.

Brian,

I have already forgotton, but have you tried removing your chip yet? If so, what are the results? Are all connectors on your PCM good and snug also?

I just ran across a NVK3 with a chip installed, I know nothing about it, came out of a salvage truck. I would be willing to trust you if you sent a an prepaid envelope to me. I don't know if you can change from NVK4 to NVK3 without a problem tho Lets let the guys chime in on that part of it. I plan on sending this pcm to Jody Tipton for a special tune or two but thats a month out from now. So I would have no problem with you paying shipping and using it for a couple of days before sending it back. Trustworthy in Texas Bryan
