Every time it rains hard my car will turn over but wont start

You need a can of wire dryer and WD40.

I have the same problem on the same car.
I replaced the spark plugs, wires, distributor cap and when it's damp and wet my car would not start. sometimes if i try for 20 minutes it may kick in but doing so after a few rainy days i blew my starter. Now I just spray my wires and cap with the wire dryer and WD40 before it rains. And if it doesn't start and it's wet outside, use the wire dryer. I heard some people used some shroud to cover their cap, but i don't know what they used as it's close to the engine and I didn't want something melting.
