Contacts inside the AFM electronic board were damaged. I used my knife and opened her up and put everything back in it’s place and high temp silicones it up and it’s good as new.
I finally got it all worked out. It was the AFM. There were several small foils of metal inside the AFM that were contacting places that they shouldn't be. removed those and now she starts up like a charm. I am sure that new fuel pump and distributor, spark plugs, and wires didn't hurt either.

@jonheld do you have similar diagram for the relays in the driver's side kick panel?
I am having trouble getting my rig to start. My situation is different, that OP. All of what I am saying is before I found your diagnostic procedure this afternoon at work, which I will go over when I get...
The old girl turned 190k so I decided to continue the baseline I started a year ago.
She got full knuckle rebuilds, new breaks in the front and back, new rear axle seals and bearings, new O2 sensors, and new tie rod ends.
