The GRAY wire i believe going to the fuel pump is the hot wire it should come on for 2 seconds with just the key in the on position this is were you should check voltage for 2 seconds then it will go away until you crank the truck.Your oil sending unit is behind your distributor that could be the cause .

You are looking at a wiring problem. Put a fuse in your hot wire and fasten it up and leave it there, unless you want to take the harness apart and replace the factory wire.
