Fuel Pump Relay

On Discovery Series I, fuel pump relay is part of relay module located at right side of engine compartment. The fuel pump relay is fed from the ignition relay and is controlled by the ECM. The relay is activated when the ignition switch is first turned to RUN position to prime the fuel system for a period of time controlled by ECM. Failure of the fuel pump relay will result in no fuel pressure. The fuel pump receives battery voltage from fuse (20-amp) No. 7 located in engine compartment fusebox and fuel pump relay.

On Discovery Series II and Range Rover, fuel pump relay is located in underhood fuse/relay box located at right front corner of engine compartment. On Discovery Series II, the fuel pump receives battery voltage from fuse (20-amp) No. 10 located in the right side of engine compartment fusebox. On Range Rover, the fuel pump receives battery voltage from fuse (30-amp) No. 10 in engine compartment fusebox.
