While I was changing the ignition module and testing the coil on the cap, I decided I would change the cap and rotor since I had also bought NOS of both. I changed the ignition module to a NOS module, and the coil tested fine so I put it back. I also tested the wire that goes to the BAT terminal on the distributor to make sure that it was getting battery voltage with the ignition on and it was. I think my next steps are to check the magnetic pickup and to make sure that the distributor body is grounded.
