Just one? You should have done both but thats ok.

Are all powers and grounds hooked up? Is there 12 volts to the coils?

The 12 volts comes from the fuse box for the feed to the coils. It sounds like a harness issue here with all the body codes.

Did it ever run?

Than you very much Roy,
I appreciate your help.
So I should have 12 volts to each coil when the ignition is on, right?

It was working fine before replacing the head gasket, maybe in the process something got damaged in the wiring harness, I'm going to test the harness.

Yes, 12 to all. Inspect the harness, maybe you got it trapped in something somewhere
