Keep critical engine circuits switching on command with the Standard Ignition RY-355, a Mitsubishi Montero relay listed as a direct-fit replacement for the 1991-1999 Mitsubishi 3000GT, 1992-2000 Mitsubishi Montero, 1996-1998 Mitsubishi Galant and 1998-2000 Mitsubishi Montero Sport. Standard Ignition calls it a computer control relay, and it is cataloged as a fuel injection relay, fuel pump relay, ignition relay and main relay. For engine-specific details, see the "Vehicles it fits" section.
A relay uses a small control current to open and close a higher-current circuit. If this relay fails, the components it feeds may not receive power. Signs it may need replacing include a crank-no-start, intermittent stalling or a fuel pump that won't run. Other faults can cause the same symptoms, so diagnose the circuit before you replace the relay.
