STALLING PROBLEMS? There are two main causes for stalling on the GM 6.5 diesel. The optical sensor is internal to the pump, but the PMD Driver (also know as FSD) can be replaced without removing your GM 6.5 diesel injection pump. Review this list of items to check before replacing your 6.5L PMD.
$200 Core Charge
DS Pump with New HD PMD (read about the HD PMD here). This pump is built to OEM standards, and, in fact, is the very same pump you would purchase if you paid up to twice as much at the dealer. Don't settle for a low-quality rebuild when you can have the assurance of a high quality remanufactured unit from an OEM supplier. Covered by our 1 year warranty. This pump can also be purchased without the PMD ($755) if you have recently purchased a PMD and now have injection pump issues.
SPECIAL OFFER: Add an FSD Heat Sync to your GM 6.5 diesel injection pump order for only $90.
Note: If you have a 1994 truck built before January 15, 1994, we need to know the part number of your old pump in order to issue a correct replacement. This is very important. The Part number is located on the top line of the ID tag on the rear of the pump. If your part number is 5068, please be sure to select correct diesel injector pump at checkout.
Note: After installing the injection pump, it is necessary to set the injection pump timing. Our injection pump timing tool will greatly facilitate this process - see related items below.
