after some minor investigation it seems as if the fuel out of the #1 delivery valve is weak compared to the others.
can delivery valves go bad?
truck is definately only running on 5 cylinders. it reacts to cracking the line on the other 5 cylinders.
EGTs are down,boost is still the same. no white smoke,but less black smoke. lift pump pressure 25psi at idle,40 under load.
this happened suddenly. fine one night running on 5 cylinders the next morning.
ideas?
