The truck has fuel and the fuel pump feels and sounds like its running but there is no fuel pressure
It is my understanding that the fuel lft pump has been replaced( updated) and is now gone back to the old way and is re installed in the tank.
I have had to put 3 lift pumps in since new, little did I know but Cummins tells me that the lift pump delivers minimal pressure and shortens the life of your injector pump.
So if that is true perhaps it is best to eliminate the lift pump and go with the new in tank pump. I plan on doing it the next time I have a problem.
Did you check the fuel filter? It can be cleaned out manually. I just hold it to my mouth and blow but make sure the gunk-side is away from you.
