Check the ignition switch its what the tumbler turns and tells the starter to start, it could also be a security wire if those had much for security i know on the older chevy cars they had a security wire going to the ignition switch that would break, it sounds like a wiring issue cause it won't even try to turn over. like he said check power and ground at the distributor but even then it should turn over with the key it ust wouldn't have spark, figure out why it won't turn over with the key first and that might fix all your problems
