i had the same prob with my cavalier 95, getting no spark and checked everything, it turned out to be the ignition module which amplfies the current to gain a much larger spark. check your ignition coil too this could also be a prob, i replaced my ig module, ig coil, dizzy + rotor arm, coil lead, HT Leads and spark plugs lol after all this car ran perfect ever before lol
