did it start after the tune-up? I did a tune-up on a blazer and it ended up being the ign rotor. Usually the metal part is 1 piece, but in this instance it is a 2 piece and mine got moisture in between the 2 and make it not fire right. I ended up using an old rotor or different design. It was a Duralast part if your curious

It runs great when dry.only when it rains it will not start.even when it sits over night while it rains then the next morning Will not


what i was getting at was mine started doing this AFTER the tune up. Did you do the tune-up becasue of this or did it start doing this after the tune-up?

Codes coming back on O2 sencer and misfiring so we changed them


to: 1/ You only said complete tune up--that phrase HAS NO DEFINITIVE MEANING .....2/ You went on to say that problem is water related--that statement has meaning.......water + electricity = bad......3/ I said arcing......4/ Andrew said moisture in rotor contact ; also suggesting arcing. 5/ you came back with .."I changed a sensor" .....6/ Bye-bye ( Shawn is justing wasting our time )

Really dude..thanks alot peace


Hey Shawn! I bet there is a crack in your distributor cap. Moisture usually will get in there after a rain and causes these issues. Try that.
