Not Ranked
12V won’t be present at coil + is because your MSD ignition is a Capacitive Discharge Ignition...
Go to the MSD website and read the tech paper "Checking The MSD Ignition For Spark" - A simple test...Next I would look at the mag pickup tech paper "Magnetic Pickup in the Distributor" another simple test.
Other possible causes would be cap and rotor not properly installed...Bad ground on MDS box. Bad connections on wiring (especially at coil where actual attachment of wire is hidden at metal connector end... The two tests above will tell me a lot...
