Ok,

You know I checked the voltage at the relay terminal only not at the pcm so when I have light of day I'll see what I can see.
Appreciate your help and patience :) Sorry I'm a little cranky this whole thing is getting better than old for me. I'll post in tomorrow
and let you know what happens.

Correction, not voltage. The PCM supllies ground. It been a long day :D
Confirm the PCM is grounding the wire for the relay.

Ok,


I've been busy so I haven't had a whole lot of time to do anything. Yeah as far as the ground for the starter relay it is testing out ok.
I talked to a guy in town here that I've had work done at before last week and he told me that they had one in the shop doing the same
thing. When I told him all that I'd done he said that beyond the shadow of a doubt it is the pcm and that they had one they could reflash
and get in there for me. Soon as I have some extra scratch that's what I'm going to do,

Thanks for your suggestions
