I have a 1993 6.5 diesel that is kicking my butt. Bought it with a blown motor and put a low mile motor in. Ran great for a few weeks. Then it started not starting in the morning. Once I got it started it ran fine. I noticed that the throttle shaft was leaking so I figured it was getting air in the system. Replaced the injection pump and for the life of me cant get it to start. New lift pump. Has fuel to the lift pump. Does not seem to be getting fuel to the injectors? Another bad injector pump? Any advice would be awesome!
