My truck is a 06 cummins (manual tranny), has a fass and some other stuff. It cranks over fine but won't fire. It does sputter a bit when first cranking but nothing after that. I can hear my fass running, the fuel isn't jelled (my espar is running and is a much smaller fuel line). It ran fine when I parked it 2 days ago. It has 290,000 kms on it. Any thoughts on what I should check? Thanks

 

Ime no expert but I would start by making sure there is fuel to the injection pump. I helped a guy get his 01 going that had simaler problem. He had no fuel at his pump but his FASS was running. It took me a while to convinse him to crack some lines loose and see if the pump was actualy pumping. After a long time of not getting fuel to the filter housing he reluctantly cracked the line loose rite at the pump and there was nothing coming out of it even though it was running.
