I am not a diesel mechanic but something I have done to help find a problem is this. Find a place as close to the tank as possible and install a low pressure electric fuel pump (4-6 psi) with a loop of clear fuel line on the exit side. Turn it on, prime your fuel system again, start it and see how long it runs. If it runs, then you probably are getting air in the fuel system. The clear line will show bubbles if you are getting air in before the electric pump. If you are getting air in below the pump, it should show up as a leak between the electric pump and the inj pump. If it runs with no bubbles and no leaks, I would question the quality of the factory pump you replaced.
I have installed electric fuel pumps on several older tired diesel machines with good results that would not give good dependable service otherwise. Yes, I know if everything is perfect, this is not necessary.

But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
