Ignition start / run question

Check the bulkhead connector where the ign hot wires pass.

Simple test, put the key in run, test the side of ballast not connected to coil. No power, bulkhead or switch is a likely culprit. If you have power, test other side of ballast. No power, bad ballast.

Disconnect the starter trigger wire at starter relay so the engine doesn't spin over
Put key in start, the coil side of ballast should have power. If not, check bulkhead wires for power on pass compartment side when in start.
