water goes into places you don't want, take air and disconnect all your connectors, all the electrical components must be free of water. Blow each connector both sides, if you have penetrating oil spray it in the connector, it displaces water aswell.


No simple fix here, hard to say what you might have done, everything from completely shorting out the control systems to hydro locking the engine and bending rods. Your best bet is talk to your insurance company, see if you have coverage, then tow it to a shop you trust for further diagnostics, then decide if it is worth repairing, remember once water gets into the vehicles electricals it starts corroding componets slowly, so some things might just quit working a year down the road.

don't drive in "flood waters" it ruins cars- if submerged, it ruins all the electronics- if this is what happened, the car is a write off- it's not cost- effective to replace the whole electrical system- and a warning to the next person who might buy that car- it may be cleaned up, but it is ruined-
