Hi all, I have a 770CH II (PINW770CH595386) (ESN:SE6081H390975) that will start and die. Machine fires up immediately and dies as soon as key is released. It will run if key is held in start position. It does read RPM when running and shows no codes. So far I have: Swapped around relays, checked fuses, changed out key switch with known good one, throttle position sensor swap with known good one, fuel filters new, tank screen is clean, connectors checked going to injector pump, multipin connectors checked between cab and engine bay. To the point of thinking its the injector pump or the controller, but I don't know which and there is too much money involved with those to just go firing the parts cannon. Any suggestions would be appreciated.
