Have you checked for spark? If no spark...Check all of the little wires that go in to the distributor and then to the coil/ignitor. I know you had no issues with fit but I have experienced that they tend to get brittle and can come unattached if you look at them crosseyed, or the insulator can crack and ark away your energy required to spark the engine to life. if that dont do it...check coil resistance...and if you've got juice to the ignitor.
