even tho you have spark from the dizzy it could still be at fault... in fact the dizzy is the only thing i can think of. If its not firing at the right time it wont start. Its usually the tdc sensor inside the dizzy or some crap like that, and it wont throw a cel either... i did this on a 96 eg, same simptoms and it was the dizzy... change it out with a known good one and im positive itll start...
