Hi Mike. So sorry you are having so many issues with your truck. I have faced many of the same problems as you have, in the 20 years that I have had my two 6.5 diesels. One big plus for me was when I bought the dignostic package from Enghs Motor, right there in Sweden. You can get the laptop computer hookup and download the program, then see all kinds of things going on with your codes and injection pump. After I hooked up my computer, I found out my stepper motor was not working, so I bought one or two parts pumps off Ebay and used the parts to fix mine. You get the shutoff solenoid and the fuel sensor light too. I paid about Can$100 each for the pumps. When my 94 one ton vacuum pump quit working, a diesel mechanic said to move the drive belt from the inside of the pulley, to the outside and it has worked well since then. I also greased the cam inside the pump. I have put several starters on, as well as alternators. Make sure your harmonic balancer is good, with not much flexing of the rubber, or it will break the crank. I have had issues with cracked blocks as well, but fixed that with a Hummvee takeout from Ted's Trucks and Stuff. You might have better luck with yours in the long run. Some over here in Alberta, Canada have gone over 600,000 km with regular service.
