Installation & Application Notes

Use clean, filtered fuel — fuel injection components have micron-level tolerances. Prime fuel system before cranking to avoid dry-start damage. Replace fuel filter whenever servicing injection components. Calibrate injectors after replacement if equipment has ECU.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a faulty shutoff solenoid is often the inability to start the engine, or conversely, the engine failing to stop when the key is turned off. If the solenoid becomes intermittent, the engine may stall unexpectedly during operation. Continued failure can lead to the inability to control the engine's running state, posing a significant operational risk.

Installation Tip

Ensure the electrical connector is clean and free of corrosion before plugging in the new solenoid. Avoid applying excessive force when mounting the solenoid to prevent damage to the housing or internal components.

Service Note

When replacing the shutoff solenoid, inspect the engine wiring harness for damage and test the electrical supply circuit for proper voltage.
