Bet I know what the problem is!
The wire going to the starter is worn and rubbing against the engine block somewhere. This is where the short to ground is. Let the wire loose at the starter solenoid and pull it around the engine and inspect it. I've been through this exact drill. Kept me guessing for awhile.
The wire from the starter that is co joined with the lead to the fuel pump bypasses the OPSS so the fuel pump operates while the engine is being cranked.
