New starter, battery, ignition switch. Intermittent starting issue. Starts three or four times back to back, won't start again (no cranking, starter won't even spin).

I can "short" the starter with a separate switch and it will fire up every time. I have double and triple checked all my work, wires are snug, ignition lock is aligned properly within the ignition switch.

I've got nothing at this point. Unless there is a lose wire or bad connection uner my dash, I don't know where else to look.

Any help is greatly appreciated. Thanks.
