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

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.

spray some 10 40 on first the distributor cap if no luck do the coil -probably moisture in one or the other I just tried it on my 96 blazer and after I did the ign coil it started.

spray wd 40 on the coil and distributor will dry out the moisture if it then you know where the problem is


Just change your ignition coil and all should be fine.
