Cummins ISM rough running
I have a 2006 ISM running on cylinders 2&6 only. Getting voltage from 9 to 16 volts through injector harness. Injectors ohm ok and complete overhead ran. New turbo, alternator, engine position sensor and bench tested ECM at Kenworth dealer off of the truck. I have no accelerator pedal response and no pressure on oil pressure gauge but I am getting oil to top of engine. Anyone seen this or got thoughts?

RE: Cummins ISM rough running
ISMs often misfire because of a faulty ECM but they usually have an active injector driver fault at the time.

Does it have oil pressure related faults?
