Posting this for a friend that does not have a computer. He owns an 05 3500 dually. He was telling me his truck wont start, the only way he can get it to start up is to fill the fuel bowl with trans fluid. Other than that if the bowl has fuel only it will not start up, pump is working. I am not a mechanic but do own an 04 3500 myself that I have not had any problems with, so really had no help to offer the guy. New to the site and told him i would post it here as there seemed to be alot of people on here who may have some advise.

 

could be injectors or fca he is not building up rail pressure

 

injector is stuck open. need to cap line one by one on the rail and crank it after each time. when it cranks you found your bad injector
