Had this issue on our 2000 986. Was getting ignition lights and cluster working okay, roof not working, radio not working, no voltage at fuse E1, engine wouldn't turn over, non starter, nothing. Was freaking out thinking the ALM/IMM ECU was kaput. Turned out to be a faulty ignition starter switch. Replaced that and all was well the car starts, the roof and radio work once more.
