Power to the coil but no spark.

We're assuming that the distributor is turning while your cranking the engine over....right? I like to test by getting the reluctor lined up with the pickup and then just rotate the rotor back and forth to generate the spark.....keeping the coil wire attached to the coil and the distributor end a 1/4 inch or so from a good ground. This gives me a bit more info regarding the pickup and distributor as well as the other components.
