Can anyone answer how I'm getting 12 volts at the low voltage side of coil #3 but the plug isn't getting any power? I don't understand that one. The only thing in the way of the 12 volt supply and the plug, is the coil - and that's brand new. What is my next logical step?
There are 3 measurements possible between 3 terminals of each coil, and you are only listing one.

The spark is triggered on the secondary (plug) side of the coil, when the ground is interrupted on the primary (low voltage) side.
