94-00 GM 2500/3500 6.5L Pump Mounted Driver (PMD)

G&J Diesel » Products Page » Chevy/GM » 94-00 GM 2500/3500 6.5L Pump Mounted Driver (PMD)

The PMD is designed to withstand engine compartment operating temperatures. Also available 6-ft harness giving you the capability of mounting your PMD somewhere else besides the pump. Saving you money and time! It comes with a one-year warranty.

NOTE: You MUST reuse your existing resistor located in the plug of the PMD or purchase a new one.
If your 6.5L diesel (with the DS4 electronic injection pump) is showing symptoms of stalling, hard starting, and hesitation, you may not need to replace the injection pump just yet!

GM Technical Service Bulletin #77-63-06Ab states that: “stalling, hard starting, and hesitation are symptoms of a failing PMD (Pump Mounted Driver) module.” These symptoms usually (but not always) set a code 35 or 36 in the 1994 – 1995 models, or a code 1216 in the 1996 – up models. Often when this problem is diagnosed at a dealership or repair shop, the customer is told that the injection pump needs to be replaced. But in most cases, the PMD module can simply be replaced for a fraction of the price.
