this car came in as non runner with no fault codes in engine but in instrument panel had u1900 can communication bus fault receive error? which cleared ok.
in data I can see an engine speed when cranking but scanner does not support rail pressure reading so local diesel specialist came and checked pressures for us and all ok,but no signal to injectors at all.
engine fires on easy start but struggling to diagnose further,autodata mentions an injector control unit on l/h side of engine bay but cannot find it.
any help or tips much appreciated.

thanks
