Keep switched power flowing to your engine's fuel injection and ignition circuits with the Standard Ignition Computer Control Relay / Fuel Injection Relay / Ignition Relay / Main Relay RY-278. It drops in as a direct-fit replacement for the 1994-1997 Ford Aspire, 1993-1997 Ford Probe, 1993-1997 Mazda 626, and 1993-1997 Mazda MX-6.
A relay like this uses a low-current control signal to open and close a higher-current circuit, delivering power to the fuel injection and ignition components it feeds. When it works correctly, the circuits it controls energize on command; when it fails, those circuits can lose power.
- Switched power delivery: passes a low-current trigger to make or break the higher-current circuit feeding the fuel injection and ignition system.
- Broad application: one relay covers several Ford and Mazda models from the mid-1990s (see the full list below).
- Signs it may need replacing: intermittent stalling or a no-start condition can occur if this relay is the cause and stops passing power to the circuits it controls.
Diagnose the circuit before replacing to confirm the relay, not another component, is at fault.
Manufacturer part number RY-278 (also RY278).
Fitment: 1994-1997 Ford Aspire · 1993-1997 Ford Probe · 1993-1997 Mazda 626 · 1993-1997 Mazda MX-6.
