i have a 94 s10 blazer VIN W thats been giving me trouble starting ONLY in the rain for the last few weeks. I got it to start last time by blowing a hair dryer over the ignition coil and distributer...there are no visible cracks in the distributer, how do i know if the problem is the coil or the distributer/rotor? And will replacing either of these fix this problem, or will this simply reoccur in another 5,000 miles thanks to another poor chevy design? Thanks alot!!
