I posted some of this as a reply to another thread but since it is largely buried I thought I would start a new one. A friend of mine and I both have 94 K2500 6.5TD's and he is having a problem with his truck not restarting after a heat soak. We have changed the PMD's out (we have about four working units to choose from and it has a PMD remote cooling heat sink) when his truck fails and it does not remedy the no-start condition. The same PMD's will start and run my truck fine. We have verified the fuel shut-off solenoid clicks on, the lift pump runs, no codes are set, and no air in the system. The DS4 itself is relatively new (less than 30,000 miles). The only thing that seems to bring it to life is to let it set long enough to perhaps cool down. We have performed many of the checks posted here associated with this issue.
