My son is racing a 2006 Mazda three in rallycross. He went through a deep water crossing and the car stalled. We thought it was hydrolock, but no. When you turn the key the lights come on, but nothing else. The starter does not make any noise. There is a key flashing on the dashboard and the power steering light is on. I understand the flashing key is the immobilizer. Anyone have any ideas?
