Have you actually checked for power and ground? Do you have power at relay? Does relay energize?

No none.
I ran a jumper to the relay and pump started running.

No fuse for the fuel system in the fuse block.
Am now investigating the main relay.
Still no power to the computer and fuel relay

Looks like power originates at starter terminal. Maybe fusible link there?

Didn't find a fuseible link, only 2 wires at the starter.
Main relay is rusted really bad inside, as is the headlight relay.
