  • [Corsa D] No crank

    Hi, I have a 2009 1.3 cdti Corsas D, this car will not crank, starter is ok if I jump the realay, so I have a control problem, I have had this on couple of Corsas d before but they would crank and the spanner light flashes. And drops they key code, but This does not turn over.
    This is what I know.
    engine does not crank
    new battery
    no communication with the ecu
    all fuses are good

    questions
    The car has come to me as a non runner

    if it has lost the key code. Should ot crank over?
    if it has lost the key code , I should still be ale to read the ecu but I canít
    they say never try to bump start a corsa D, Why? What does it do?

    Not quite sure where to start with this one

    any help would be very much appreciated

    The BCM module throws a wobbler sometimes when you jump start the corsa D and kills the immobiliser.
    Sometimes just by disconnecting the BCM module and reconnecting it with the battery still connected brings it back to life. If you've got op-com sometimes you can reprogram the Ecu depends how much of a spike it took from the jump start.
    If not the cheapest option is to get a second hand ECU kit and fit the hole lot .

      Hi Restorer, Yes I know what you are saying, I have done a couple of these in the last few years, But I am sure that they both would crank over, This one does not, This is a CDTI and the ones I did where petrol. so that might be the difference.

      The other thing that concerns me is I have no communication with the ecu ? I will test the power and feeds, Not easy to get to thought.


      Thanks for the reply

        When you say no communication with the Ecu I presume you mean at the diagnosis plug. If you've got Autodata you can test the outputs on the pins from the ecu.
        Like power going into the Ecu pins and volts ohms at the sensors on the engine.

            i dont know much about ecus' etc, so cant help there. But this morning I forgot to depress the clutch on my Yaris and it wouldnt crank until I did. I always leave cars in gear when parked and normally depress the clutch out of habit. So I cant remember if my Corsa 1.3 cdti also needs this. (Its 1500 miles from me at present) Could it be that you are not doing it, or the switch that detects you doing it is faulty?

                I took the ecu out today and water has seeped in. gave it clean and still no communication with the ecu. I think it is goosed.
