95 5.8 no start in rain
 

I have a 95 f150 5.8. It will crank in the rain but no spark any ideas what the problem might be? I heard if you use wd40 around distributor it will work its only when there is alot of moisture in the air.

Pull your distributor cap and see if there is any moisture inside. Last time I saw something similar it was a cracked distributor cap and replacing it made the problem go away.

We replaced it 2 years ago but ill check it an get back to you. i have to drive my v10 around 10.4 mpgs worth
