Fuel pressure drops when accelerator pressed ? sound like a bad lift pump.

As you can see from Sven's pictures, the PMD (Pump Mounted Driver) is mounted on the side of the injection pump. It amplifies the computer signal to drive the stepper motor that controls your injection pulses. PMD fails = no fuel inject = no run no more! They do it because it eventually overheats mounted to the IP. Your engine will just shut down, be hard to (re)start, run erratically, and it will do this randomly. Once it goes bad, replace it, and mount it on a cooler. Also, check Walt's FAQ section on his SS Diesel Supply web site for more information, just click above on the SS Diesel Logo.

Hope this helps.
