Engine Shut-Off Solenoid Test
A shut-off solenoid failure can result in run-on, or a no start condition. The failure may be with the solenoid, or with the related wiring (Figure 3-12).
1. Connect the scan tool.
2. Select Miscellaneous Tests, Engine Outputs, Injection Pump, then Engine Shutoff.
3. Use the arrow keys to toggle the solenoid Off/On and listen for the solenoid to activate or click.
4. If the solenoid does not activate, perform wiring tests with a DVOM (Figure 3-12).
5. If the wiring tests OK, replace the solenoid.
