Last night me and my wife drove my jeep around in the rain. We weren't going fast cause it was an housing area. Went through a puddle about calf deep. The jeep died. I took off the air filter it was soaked. I towed it home. I took off the air manifold inlet. And vacuum out water. Drained the oil and there was a cup or two of water. Then took off spark plugs some drops of water in a few of them. Cranked the engine over by hand and cranked fine. Says I have a p0113 which is the iat sensor. The jeep won't turn over with key at all though. Just one click and that is it. Any suggestions or am I missing something. Thx again

With that much water you most likely shorted out the IAT sensor harness. You'll most likely need to replace it. The biggest issue is you'll need to purge all the water out of the engine.
