1994 - 2002 GM OBS Truck 6.5L Diesel PMD / FSD Tear Down Rebuild (Chevrolet GMC w/ Stanadyne 39405)

This video goes over my procedure for tearing down and rebuilding the grey Stanadyne PMD (pump mounted driver) model 39405. We also go over improvements during the rebuild to its reliability. The PMD is unique to the DS4 electronic injection pump equipped GM 6.5L diesel engines. Sometimes you will see the PMD referenced by GM as the FSD (or fuel solenoid driver) too. Both PMD and FSD terms refer to the same part. This particular component of the 6.5L diesel has an extremely high failure rate historically, regardless of whether you have the genuine Stanadyne one sold by GM, or aftermarket. They will all fail eventually, without improvements to heat dissipation. The best point to relocate the PMD from its factory mount on the injection pump, thermally for better heat dissipation, is the front bumper cutout area. This video was inspired by the fact that Stanadyne discontinued and stopped manufacturing PMDs back in 2015. The grey model 39405 PMD was introduced in 2009. Remaining inventory of the grey 39405 model PMD is being sold only via Alliant Power under their number AP63486. Details of this announcement here: https://www.dieselforward.com/file/37... The vehicle shown is a 1999 Chevrolet Suburban with the 6.5L Turbo Diesel engine option. It was upgraded to the latest Stanadyne PMD model 39405 which is gray in color, not black, in 2010 and has a revised Stanadyne factory wiring harness and resistor circuit board design to match. However, the procedure and rebuild shown is applicable to all grey Stanadyne PMD models across Chevrolet, GMC, and Holden as well as the earlier black PMD Stanadyne models. This approach can apply to aftermarket PMD suppliers such as Flight Systems as well (which uses the previous black Stanadyne PMD wiring harness). The GM 19209057 PMD you order as a replacement now is made by Flight Systems and can be applicable to this procedure as well. Applicable to 94 95 96 97 98 99 and carry over model year 2000, 2001 and 2002 old body style (OBS) trucks and vans from Chevrolet, GMC , and Holden such as the Suburban Tahoe Yukon Silverado Cheyenne Sierra and Express.
