It may help you to understand how the steering module does its work. Introduction and Location. The Rover SD1 Efi Steering Module activates the Main (Efi) and Fuel Pump relays in a safe sequence. Its never a good idea to by pass any relay unless you are doing so for testing purposes. The relay allows low amps to control a high amp circuit. By passing the relay can create too many amps to go through a smaller wire that controls that circuit. Additionally, in most modern vehicles the PCM controls the fuel pump relay by providing t,. You must measure the fuel pressure at the fuel rail. A schrader valve is provided for a pressure gage adaptor. It should read between 32 to 42 psi. Jumping the relays (automatic shutdown & fuel pump relay) is not a good idea and will require a Haynes manual. The crankshaft & camshaft sensors can also cause the two relays to trip. Check the relay's near the ecu. There should be a few of them, but the one you want is for the fuel pump relay. It should have 4 wires going into it. Black/white Blue/Black Pink Pink/Black If you ground the pink wire, that should create a closed circuit and send power to the fuel pump. Fuel pump relay No. 2 Or Additional relay, fuel pump .
