No start condition
Found exterior injector harness connector wires shorted, Replaced harness. Cam position sensor wiring shorted, repaired short. Internal injector harness shorted at #3 and #6 injectors, repaired short. Primer pump plunger leaking while priming, replaced. Checked IDM/ECM fuses and all grounds at battery box/starter/engine. Active codes on all Injectors while cranking low voltage or open circuit, using generic reader. We are a Kenworth dealer and have no Navistar Software. I'd like to test Injector driver module but have no specs.
