Product Description
Restore proper start and shutdown control on your first-gen Dodge Ram with the CUMMINS 3903575 OEM FUEL SHUTOFF SOLENOID. This solenoid mounts on the VE rotary injection pump used on all 1989–1993 5.9L Cummins trucks and provides the critical electrical-to-mechanical actuation that allows your engine to start and stop correctly. A weak or failed solenoid can cause extended cranking, random stalling, or the inability to shut off the engine. This is the genuine Cummins replacement—not an aftermarket copy.
The VE pump's shutoff solenoid is notorious for age-related failures, poor electrical grounding, and worn internal springs. Installing this brand-new 3903575 Cummins solenoid restores factory function, quick startup, and reliable shutdown control so your first-gen stays dependable for daily use, towing, or restoration projects.

Installation Notes
- Ensure clean electrical grounds — VE pump solenoids are sensitive to poor grounding.

FAQ
WHAT DOES THE CUMMINS 3903575 FUEL SHUTOFF SOLENOID DO?
It opens the fuel passage inside the VE rotary injection pump when the key is turned on, allowing the engine to start. When the key is turned off, it closes the passage and shuts the engine down. Without a functioning solenoid, the engine may not start or may fail to shut off.
IS THIS A GENUINE CUMMINS SOLENOID?
Yes. This is a 100% genuine Cummins OEM 3903575, not an aftermarket reproduction. It meets factory voltage, plunger travel, and durability specifications.
WHAT ARE COMMON SIGNS OF A FAILED VE PUMP SOLENOID?
Symptoms include intermittent starting, random stalling, the engine continuing to run after the key is turned off, burnt or overheated solenoid coils, or the plunger sticking open or closed.
DO I NEED TO BLEED THE FUEL SYSTEM AFTER REPLACING THE SOLENOID?
Usually no, as the solenoid sits externally on the VE pump. However, if you disturb fuel lines or have air intrusion, a quick manual bleed at the filter housing is recommended.
