My car was in water and won't start now.
If you went through water and your engine ingested the water and stalled, then you would have to have all the spark plugs removed and the intake cleaned out. The engine would need to be turned over with the spark plugs out to see if internal engine damage happened. If it did then the engine most likely will not turn or turns part way and locks up. If you are lucky the engine will blow out the water and after drying out the engine may start. I recommend you have a mechanic like one from YourMechanic give your vehicle a complete inspection. Most of the time the engine bends rods and the engine would need to be replaced.
