The normal power to the fuel pump goes through the oil pressure switch.
The fuel pump relay is to charge the line for easier startup. It is indicated as a "primer" on my drawing.
The orange wire at the fuel pumper oil pressure switch comes off the 20 amp ECM/fuse and is splice to the normally open contact on the fuel pump relay which is controlled from the ECM pin F6
The grey wire on the oil pressure switch feeds power to the pump itself.
