Product Overview
Mounted in the electronic DS4 injection pump, the shutoff solenoid controls whether fuel is admitted for engine operation. A failed solenoid can cause a crank/no-start, sudden stall or an engine that will not respond normally to the ignition shutoff command.
Stanadyne 33072 is an older reference commonly cross-listed to GM/Chevrolet/GMC 6.5L electronic-diesel applications from the mid-1990s into the early 2000s. Because mechanical DB2 and electronic DS4 pumps use different components, verify that the vehicle has the DS4-style pump before ordering.

Frequently Asked Questions
Q: Does this fit a mechanical DB2 injection pump?
A: No. This listing is intended for DS4 electronic-pump applications.
Q: Can a PMD/FSD failure look like a shutoff-solenoid problem?
A: Yes. DS4 systems have several electrical failure points, so diagnose the pump driver, wiring, power supply and solenoid circuit before replacing parts.
Verify DS4 injection-pump type and original solenoid/reference number.
