1994 Chevrolet Lumina APV Question: My van will not start when it is wet out. otherwise it starts and runs terrific

I only have a problem starting when its wet out and my van has sat more than 8 hours. I was told most likely a crack in the distributor cap.Any ideas or suggestions? Also any step by step instructions how to change cap and rotor as I;ve heard they should both be done. -
Answer 1
Does not have a distributor type ignition system. Suggest getting a mechanic to check it out! Very tough to access the ignition componets on this vehicle, even for a pro. -
Answer 2
Try spraying plug wires with wd40 -
