- One part, four catalog names: Standard Ignition lists the RY-401 as a fuel injection relay, fuel pump relay, ignition relay and main relay.
- Engine coverage: Cataloged for All engines on each listed application.
- Quantity: Each listed application uses one relay.
A relay is an electrically operated switch. A small control current energizes its coil, which closes contacts that carry the heavier current for the circuit it serves. That lets a low-current signal switch power to demanding components such as fuel injection, the fuel pump and ignition.
Signs a relay may need replacing include an engine that cranks but won't start, a fuel pump that doesn't run when the key is turned on, intermittent stalling, or a relay that no longer clicks. Fuses, wiring, the pump or ignition components can cause the same symptoms, so confirm the relay is the cause before replacing it.
