Posted:12/11/2008 08:04 Founfd the issue to be in the new fuel pumps and that they were flawed. The back pressure relief on the pump was sticking. Manufacturer changed from using a metal bearing to a plastic one and it was swelling and blocking the pump up. Took apart pump and removed that part. Also the motor in the pump was spinning inside itself and put a pin into hold it in place. It takes a little long to crank to start but the truck fires up even in this subzero temps. Better than my neighbors Dodge...lol The info I found on the pump to assist in repair was in a Jaguar website that has the exact same pump in it. Bosch was the manufacture of this High pressure pump.
