The no-start condition can be caused by the "pick up coil" in the distributor. Cheap part, but the distributor has to come out and come apart to change it. The pick up coil is a weak link in GM distributors of that vintage. I replaced my entire distributor (91 Pontiac) with a MSD Pro Billet unit and the problem was completely solved.
Experience is something you don't get until just after you need it.
