the way I learned about why you need to keep the distributor cap dry was as follows: I got the bright idea to wash my old 89 camary wagon's (gone now, great car) engine, so I popped to hood and sprayed the S##t out of it. literally. anyway went to start it up the next day and to my absolute horror the car did the same thing your car seems to be doing , had electricity, tried to turn over but wouldn't. I had no idea what was happening and suspected the worst. turns out I had gotten water in the distributor cap. Because you notice your car's symptoms when its wet outside, humidity or rain, I think it might be a good idea to, if you have not already, at least inspect the cap and plugs.
