    hello to all memebers,
    I have 2006 a6/c6 3.0tdi BMK manual, she is not starting just cranking, vcds gives no faults related to this. I disconnected injector cables but gives me no fault too?.
    I can prime fuel pump by doing output test, installed to little filters in place of original filter to see fuel flow and return live ,cleaned grounds and lives, checked fuses, checked ecu for water all clean and dry. also hiwire fuel pump just to see it pumping all good, car start with easy start spray, but stalls instantly if spray stoped. injectors calibration from ecu is
    cyl1 -4 0 1
    cyl2 -2 12 2
    cyl3 0 0 2
    cyl4 0 2 0
    cyl5 -4 0 0
    cyl6 0 4 0
    im out of clues what to do next? thank you for any input
    injectors and fuel pump have no power to them with ignition on

    Do you have fuel pressure from the high pressure pump?

    hi CRASHER,
    could you explain how to do that?
    then cranking requested was something like 348bar and actual climbed to something similar, so I beleve so. I installed transparent filter on feed and one filter on return hoses from original fuel filter, then hiwire fuel pump in the tank, then feed filter was with diesel I started to crank engine then return filter filled up with diesel but still not starting. no voltage to injector wires or fuel pump in the tank.

    There was a post on here recently that had a similar issue which was the crankshaft sensor not seeing a signal due to a damaged flywheel.
