Be sure the coil you are using is compatible.
With the key on check to if you get a strong spark at the center coil wire while grounding it and while jumping the violet & green wire. Next crank the engine with the distributor cap off, verifying that the rotor is spinning while cranking the engine. If you have strong spark at distributor wire and if distributor is spinning move to the module in the distributor. Use an ohm meter in the connector to check the module for continuity. If there is none replace it. The module and the spinning reluctor create the voltage signal that swithches the MSD internals and causes the electrical field in the coil to collapse creating the spark that goes to the distributor and is directed by the rotor to the correct plug wire. Sound simple huh???

PS: With a little ingenuity you can use the armature (the part in the distributor with the windings) from a standard mid 70's application.
