Hello and thanks for using JustAnswer.I will try my best to help you with your question.
You will need to do a manual compression test on all 6 cylinders. This will evaluate the basic mechanical parts of the engine. Also, inspect the spark plugs while they are out and see if there is any water in the cylinders. Each cylinder should be around 175 psi. This is the best way to start diagnosing this problem. Also, checking trouble codes in the PCM.
Do these test and please let me know the results.

Hi Mr. Penland, There is no water inside the cylinders. Is it possible the fuel pump got wet and shorted out. It was not in deep water.
Expert:  A. Penland replied 2 years ago.
The fuel pump is on top of the fuel tank half way up the vehicle. It is sealed to the fuel tank. You can also disconnect the fuel line to the fuel filter and turn the key to on and see if you get fuel from the fuel pump.
