An Energise to Stop Solenoid (ESOS), a key component of the fuel system. Its job is to immediately cut off the fuel supply to the injection pump when the ignition key is turned, which shuts down the engine. It is an essential component for the safe and reliable shutdown of the power unit.

The list above is for reference. Before purchasing, we recommend visually comparing the solenoid with your old part.
Problems with the shut-off solenoid often result from contaminated fuel. While replacing it, check the condition of the water separator and the fuel filter. Regular use of high-quality REDX filters protects the precision components of the injection pump, including the solenoid, from seizing.
The shut-off solenoid is a critical safety component that allows for the immediate shutdown of the engine. Its failure can be frustrating and prevent normal operation, and in extreme cases, even prevent the machine from being turned off in an emergency.
Replace the solenoid if your machine:

The inability to shut off the engine is a classic symptom of an ESOS solenoid failure, which has stuck in the open position. Other causes, like a problem with the ignition switch, are much rarer.
2. The engine starts for a second and then immediately dies. What is the cause?This is also a typical symptom of an ESOS solenoid failure. It means the solenoid is receiving the "start" current but is not receiving or holding the "run" current, causing it to immediately cut off the fuel. This could be the fault of the solenoid itself or a power supply issue in the wiring.
3. What's the difference between an ESOS (Energise to Stop) and an ETS (Energise to Run) solenoid?An ESOS solenoid (like this one) needs a pulse of current to cut off the fuel and stop the engine. With an ETS (older type) solenoid, it's the opposite – current is needed to open the fuel supply, and cutting the current stops the engine. They cannot be used interchangeably.
