Ok so with no battery connected it would not be possible and would probably damage the alternator/charging circuit, but in theory if you had a run down battery with enough power for ecu, fuel pump but not enough to turn the engine over it could possibly be done??
Wonder what the min voltage the ecu needs?? Could it run on eg. 10v?
There may only be one way to settle this!!!
