    Default Problems after locking E40 ECU. Won't start

    After the locking procedure the ECU hanged and then i had to remove power from the batt.

    Did a PCM lock and the car will not start...

    Tried unlocking back and vat relink and everything and it will NOT start.

    There is NO fuel pressure.

    Any help? Ideas?

    Fried this PCM?

    I have full flashed everything back and removed the lock.

    Thanks

    Sounds like a pretty strange thing that has happened there.
    I have heard of the occasional E40 going off in to space at the end of a full flash, but pulling the battery lead always returns them to life.
    Is it a manual? Maybe it needs a clutch learn as well for some reason after it had a little melt down?
    I no longer monitor the forum, please either post your question or create a support ticket.

    its an auto... i'm going to get another PCM.

    I think it "fried". I can read and flash to it... but.. it will not command fuel pressure. I don't get why.
