I see you caught yourself after chucking that ball of crapola at me. But after admitting you were on feces, then apologizing, I forgive you AK.

Thank you. You are such a putz. That must be why we all get along.

Lads,
Update. As it turns out the relays are good and the voltages are fine. I then went down to the Inertia Fuel Shutoff switch and pulled the connector. I measured the voltage across it (with the ignition set to run) and I found 0 volts from the fuel relay supply. I did find 12 volts in the circuit that supplies the fuel reset switch indicator... however the connector is uncoupled from the switch.
Anyhow I posted a pic of the wiring diagram and my "analysis".

Update: the brand new battery I installed went dead overnight. My thoughts are that there is an underlying electrical problem I need to solve. So I decided to go back to basics and start at square one. I charged my battery overnight then I set up my multimeter at the battery negative terminal on 10 amp scale. With no key everything off it reads .17 amps then jumps to 6 amps for 30 seconds then back down to .17 for 30 seconds then back up to 6 amps for 30 and continues ...
Does anyone have a clue what this could be?
Thanks for reading.
