I've replaced the fuel pump relay no luck. I have tried to jump the orange and gray wires I hear the fuel pump kick in and the truck started. When I pulled the jumper it died. Could it be the fuel pressure/oil switch? If so is the a way to bypass it long enough to drive it 5 miles home? Thank you

The fuel pump relay powers the pump for 2 secs when the engine is cranking and the oil pressure goes above 4psi this is where the oil pressure switch powers the pump. Now when you remove the relay and it dies out then the oil pressure switch is defective.

Could also be the computer controlled of the FP relay circuit.
