12 Volt Diesel Stop Solenoid for Engine Fuel Shutdown Control SKU: QT58771

When diesel engines refuse to shut down or keep running after you turn the key off, a failed stop solenoid is the usual culprit. This 12-volt solenoid instantly cuts fuel flow when de-energized, preventing dangerous runaway conditions and ensuring your engine stops precisely when commanded.

Why This Solenoid Matters

• Prevents runaway engine conditions that can damage injection systems
• Engineered for the vibration, heat, and fuel exposure of diesel applications
• Compact design fits tight engine compartments without modification
• Reliable operation through thousands of start-stop cycles
