His truck doesn't have a dist cap , and it is coil on plug so it would have to be several coils for a no start. I would check all connections , especially the one for the pcm . Sounds like a loose connection and the moister is causing it to short / arc . One trick that worked for me on a Stang I had was spray each connection with wd 40 and let sit for a while . From what I am told the wd forces the water out .
