Good To Know
Q: What happens if this solenoid fails? A: The engine may not shut off when the key is turned off, or it may fail to start because the fuel supply remains closed. Replacing it restores proper engine control.
Q: Can I install this solenoid myself? A: In most cases, yes, as it mounts directly to the fuel injection pump; however, consult your engine manual to ensure correct wiring and alignment.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
