3126 cranks but will not start

This is on a piece of military Equipment DV100 deuce. We have tried everything sensors,pump,ecm,fuel regulator,etc...

When it first stalled it was like it was out of fuel so checked the filters and they were full so then we drug it into the the shop and started to T.S.

Hooked it to ET and it had two codes and a bad knock when turning it over. codes were 164-11(39) and injector 6 current high.Changed injector six with o-ring the knock went away but still there is the 164-11 and everything is new.   thanks ahead of time    we are beating our heads on the wall
