Thank-you spencevans.... You don't think it is the magnetic valve? I want to back it off and see if it fires but I can not get a wrench in there. The Filter housing is all of five inches away from the cut-off valve. If I knew the size of the wrench I can bend one to fit in there to back it off. Once I get that done and nothing then it is on to the timing. I mean, I have removed stuff there is no stopping now. LOL
All I can tell you about the truck is that it ran until the Turbo was rebuilt and reinstalled, after that it did not run. I would assume that the pump was never rebuilt and you are probably right... It is going to be an interesting winter without firewood..
