This is a tough one. The DME definitely had a problem, as they are not supposed to be full of water. Starting the car with a wet DME will most likely damage the unit. Unfortunately, it may have damaged some other stuff on the car as well when you tried to start it wet. I would check the crank and camshaft sensors, as the engine will not fire spark without these working properly. Also, check the connector to the DME - if that was wet as well, then there may be some rust in there that may be causing the connections from the sensors, coils, and other components to fail to be connected to the DME. Good luck!
