My 95 z28 won't start in wet weather. I've done a full tune up (plugs, wires, opti) but it still won't start in the wet. Once it fires up it runs fine. I'm thinking it might be either the coil or the ignition control module. Any thoughts? Thanks!

 

when it wont start check for spark. could be a connection or like your sayin coil icm fail. could also be water in air cleaner
