Welcome to the site!
Are you running the factory-style electronic ignition, or aftermarket like Pertronix or MSD or ?

At min, you need a meter, test lamp, jumper alligator clip leads
Turn key to run, measure coil + terminal to ground. Should have somewhere from 6--to 10V, not much lower and not much higher.
With meter clipped in place, crank engine with key and watch meter. While cranking, coil+ should see "same as battery" IE if battery sags to 11V when cranking, then coil + should be about same.
Disconnect coil wire and "rig" preferably a copper core wire--even a low voltage wire hung out away from metal--to a test gap or even a plug. Crank engine watch for spark
With key in "run" disconnect distributor connector. Take up harness end, and tap the bare terminal to ground repeatedly. You should get one single "snap" spark at the coil each time.
ECU box MUST be grounded. "Wiggle test" all connectors, and ESPECIALLY vigourously work the distributor connector several times to "scrub" the terminals. and to "feel" for tightnerss.

IF you're using the factory system, tell us how you installed it on your '64, and which one you installed- four pin ECU (single ballast) or five pin (dual ballast)?
Pertronix, problem solved I had to adjust the air gap on the magnetic pickup
Thanks doug
