I have issues with engine starting when cold outside or after rain. This only happens when engine is cold and has not been started for a day or 2. Distributor cap does not have any condensation inside but does seem to corrode on contact points. Engine turns over fine, has fuel and spark. When this happens engine will not fire and after awhile it will start to fire and lock up when it fires then continue cranking. After repeated attempts it will start and run fine, can be shut off and start right back up with out any issues. It could take a few tries to a few hours of trying before running though. I'm leaning toward a distributor or timing issue. Am I on the right track or has anyone else had this same problem?
