    Fendt 820 Erratic Starting

    2009 Fendt 820 (low hours) - when we start it, cold or hot, it fires on what seems some cylinders then seems to take a few engine cycles to completely fire up.
    Running alright when hot.
    When trying to start - it brings up EDC symbol and fault code 1.2.78 injectors of cylinder bank 1 short circuit, and fault code 1.2.7A injectors of cylinder bank 2 short circuit.
    We have tested all wiring between ECU and injectors for shorts and continuity, also injector coils - no faults.
    The Dealers tool on these models can't test it any further.
    Any ideas?
