Cranks but doesn't start using the key. Starts when using a remote starter switch.

So the problem is in the Ignition 2 circuit. Whether its at a connector, a damaged wire, or in the key switch itself we do not know. But those are the places you have to look.
As of yesterday it appears mine has an ignition 2 open circuit issue because it cranks but won't fire. But if I let the key snap back to run real fast some times I get lucky and ignition 1 goes live while engine still spinning and it starts. Once it starts runs perfect. Original '69 ignition switch. New M&H harnesses under hood and new everything electrical wise under hood too. Have new switch coming but gonna have to ohm out that circuit to verify where the problem lies.
