If you can, figure out how deep the water was under the hood. Concentrate on the starter, alternator and the electrical connections under the hood. The spray stuff mentioned in another post is LPS1, it is a water displacer. Given enough time, the water may dry out and things might get back to normal. Good luck and always look for the high ground before you park.

Update; changed all the spark plugs and the replace a fuel injector, so far all misfire problems have ceased and the truck is running back to normal, including the battery dying. Engine is popping p0401 code so I'm going to look into cleaning out my EGR valve and see if Thatll fix the code. In the mean time I'm looking into replacing the plug wires and begin doing some preventative maintenance as you guys mentioned above.
Thanks [MENTION=154062]little nail[/MENTION], ill defiantly start checking out the alternator and starter as well as the trans wire harness like Marc D suggested.

At least U got it out of the water immediately not giving it days of soak time. Mine had a flash flood last summer, when I got home the water was rising and I waded out thru Knee deep to the rocker panel high water and slowly pulled it up on the hill of the drive. All OK but good to get home with all the intersections having 1 foot of water in them and the water rising another foot during the next 20 minutes.

One other thing that wasn't mentioned is it wouldn't hurt to have the rear end drained and refilled with new fluid. To do that you will need black RTV silicone, 3 or 4 quarts of 75W140 synthetic gear lube, and if it's a locker a bottle of friction modifier. Water can seep in through the vent on top and cause corrosion on the bearings in the rear end. Hope you can get it all straightened out.

Disconnect battery and get it cjarged. Do not jump start it.
