Maybe a cold solder joint or cracked land on the printed circuit board.

parked
I left mine parked outside for 2 months, it drained the battery, I tried to charge the battery trough terminal under hood using body ground, seemed to draw a lot at first connecting, then seemed to charge OK but not completely, then I connected charger directly to battery and charged overnight , still no start,
I then replaced battery and still no start, Dealer said modules not communicating and is replacing the ECM and EBCM to start anyone know whats going on.
