Keep power flowing to the fuel-injection system with the Standard Ignition Computer Control Relay / Fuel Injection Relay / Main Relay, part number RY-1018. This relay is listed under all three names and installs as a direct-fit replacement for the 2002-2005 Subaru Forester [All] and the 2005-2006 SAAB 9-2X [All].
An electrically operated switch, it uses a low-current control signal to open or close a higher-current circuit that feeds the engine-management electronics and injection components. When the original relay is the cause of a no-start, intermittent power loss, or an injection circuit that won't energize, RY-1018 replaces it.
- Relay function: switches the fuel-injection/main power circuit on the low-current command from the control side.
- Direct-fit replacement: for the listed Subaru Forester and SAAB 9-2X applications.
- Multi-name part: cataloged as a Computer Control Relay, Fuel Injection Relay, and Main Relay.
Signs the original may need replacing include intermittent or lost power to the injection system and hard/no-start conditions traced to this circuit. Diagnose the cause before replacing, since these symptoms can have other sources.
Interchange: Manufacturer part number RY-1018.
