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

Re: No crank no start Chevy Trailblazer 2002
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
