Frequently Asked Questions
What is a fuel shutoff valve?
The fuel shutoff valve is a safety device that cuts fuel supply to the engine. It is commonly used on diesel engines to shut down the engine since diesels do not have a throttle to cut airflow. When this valve fails open-circuit, the ECM cannot control fuel delivery.
Why will my engine not start with P0005?
If the fuel shutoff valve cannot be energized due to an open circuit, it remains in its default closed position, blocking fuel to the engine. Without fuel, the engine will crank but not start.
Can a blown fuse cause P0005?
Yes. A blown fuse in the fuel shutoff valve circuit will cause an open circuit condition. Check the fuse box for the fuel system fuses before replacing more expensive components.

Step-by-Step Diagnostic Procedure
-
Check all fuses related to the fuel system and fuel shutoff valve circuit
-
Inspect the fuel shutoff valve connector for corrosion, backed-out pins, or physical damage
-
Measure resistance across the fuel shutoff valve solenoid; an open reading confirms a failed valve
-
Trace wiring from ECM to shutoff valve checking for breaks, especially at flex points and connectors
