First thing I would try is to disconnect the battery for about 20-30 minutes. This will reboot the system.
If the problem persists I would look at the ECM/PCM. You may want to disconnect any connecters and check for corrosion on the pins You can also get a spray for electronic connections which will help clean oxidation from the pins. Since the truck was submerged this might be a good Idea. Just make sure the battery is disconnected when you spray.
Check all the ground connections you can find, clean if necessary.
It is possible the ECM/PCM is bad. and will need to be replaced.
Good luck.
