Remove the spark plugs. Blow it out really well. Crank the engine. Let it dry. Should work ok. Happened to my friends grand am.

Pull the spark plugs, crank the engine, change any fluid that has water in it. You likely have water in the engine oil. I'd also check the transmission fluid. If it spent much time sitting in water, check the differential fluid. You probably need to change the air filter. Hydro locking an engine can bend/break connecting rods and valves. A bent valve stem can cause the piston to hit the valve breaking the valve and/or piston top. When you start the engine listen for expensive noises.

Good luck.
Keep in mind that free advice can frequently be worth less than you pay for it.

I almost forgot about this thread lol anyway I have a new engine now. The water wasn't that deep but I was just driving way to fast through it because I was being dumb and wreckless and the pistons were bent and the engine was just useless. Learned my lesson lol bought an engine from jasper and when I got it it sounded terrible so I took it to get looked at and turns out a piston inside the new engine jasper sent me was bent :/ lol so they paid for my jeep to be towed and sent me another new engine free of charge for their mistake. Back on the trails now but riding much smarter lol
