My van wont start when the air is damp. It starts every time the air is dry and runs good. I have changed spark plugs and wires, rotor and distributor cap and Mass Air Flow sensor. Any ideas what else to check?

one thing I would do, is use dielectric grease on all of my connections, all the ignition connections anyway. also if you have any exposed fuse/relay boxes in the engine compartment, make sure you get them covered, because obviously moisture settles in on one of the electrical components, and when you get the no start, on days that is humid or a lot of moisture out, the moisture tends to settle under the distributor cap, just check when its wet out, I garuntee, you'll see condensation. so it will be imperative to use the grease on all of the contact points in the cap
