Product Overview
Controls fuel shutoff on the 12-valve 5.9L Cummins used in 1994–1998 Dodge Ram 2500/3500 trucks. The solenoid must pull in during start and remain held in the run position after the key returns from START.
A classic failure symptom is an engine that starts only while the key is held in START, will not start at all, or must be shut off manually. Before replacing the solenoid, check linkage adjustment, relay power, grounds and battery voltage.
Key Features & Performance
- Provides positive electrical actuation of the diesel shutoff mechanism.
- Useful for no-start, start-then-die or no-shutoff complaints after wiring/linkage checks.
- Reference-number matching helps avoid visually similar solenoids.
