If all these are good it is very likely that you have a faulty instrument cluster.
To repair this it will need to be sent to an AC Delco Repair facility.
Turns out cluster was dead. I checked out everything you suggested and found a wrecking yard that had a cluster. They let me plug it in and it worked. Turns out the GM had a recall of sorts on mine and other GM vehicles of certain years on instrument clusters. Since my mileage was over they at least are replacing the cluster and I pay the labor to install.
You got me going in the right direction and I finished it off with some computer research. Thanks LJ
