      Driving me crazy! Just wish it was driving me. Truck will start but dies after a few seconds. I have tried bleeding the fuel lines at the top of the injectors. Truck seemed to run better but did not solve the problem.

        Just to pick some brains here….could lack of spark cause a dumping of fuel (given there’s no issues with the fuel delivery system)? Given its a diesel, could this be an internal issue such as blow-by, burnt valve etc? I’m just curious of the compression in this scenario.

          Turned out to be fuel system not holding pressure dur to leak in the fuel filter housing, replace o-rings on fuel heater and replace volt. reg. that was not allowing the batteries to have sufficient oooomph. Received these tips on this site. Thanks for your reply.

            Good deal. yeah a leaking fuel canister can cause the high pressure pump t get air in it and cause all kinds of issues.

            There is no fuel pressure regulator on that system, the high pressure pump handles pressure regulation internally.
