Hello,
Sometimes just taking the distributor cap off and leaving off for a while, allows everything inside to dry out.
Otherwise check to make sure the "fork" connection on the wire end of the ignition points did not rotate when you installed the new condensor. If the "fork" rotates enough to touch the breaker plate in the distributor it completely grounds out your ignition and the engine will not start.
Also this small attachment bolt for the condensor has three plastic insulators to prevent an electric short. Make sure these are in place. They consist of two flatplastic washer-like insulators and one plastic insulator sleeve as the small bolt passes through the distributor housing. The insulator sleeve may have disintegrated over the years and the small bolt may be touching the dist. housing. In a pinch you can use one or two small rubber o-rings in place of the insulator sleeve.
There is an easy way to trace the path of the electric current to the distributor with a 12 volt test light. Open the distributor points manually and insulate between them temporarily with a piece of plastic or paper. Turn on the ignition and check the ignition point half tha has the wire on it, with your 12 volt test light. It should light up. If not disconnect the primarry wire from the coil and test it. If it lights now, the problem is at the distributor connection.
