Well this morning after PT (im in the army) I went to jump in my truck... and now it wont start at all. Just cranks and cranks and cranks. Nothing. I was thinkin about going back and changing the fuel filters, or something.... I dont know Im stuck. I wanna stay away from the stealership........ just wondering where to start.
Being an '06 model year, it sounds like you have a high pressure oil system leak at the STC fitting and/or the dummy rail plug(s) on the high pressure oil rail(s) have torn the lower o-ring(s). Having this problem will give you the exact symptom you describe. You can change your fuel filters if you want, but this will NOT fix your problem.
May I also suggest you refrain using the term "stealership" in your posts, in the future, since the very people you are seeking help and information from will more than likely be "stealership" employees like myself (see my signature). FYI, if you are less than 100,000 miles this would be covered under your diesel engine warranty with a $100 deductible, which sure as hell beats having to pay the retail cost for this repair.
