pony lost its spark(le)

[Setinconcrete]

I've a 3yo daily riden atm50-a1.
Well maintained, stopped for gas on the way home, and then it wouldn't start.
Lights work, turns over just fine.
Is getting fuel.
Fuse is good. (Just replaced cause I broke it taking it out)

Still no spark.

Kill switch, new.
Cdi, new.
Regulator, borrowed a working one.
Coil and plug. New.
All parts are brand new and still no spark.
What am I missing?
I have power to the cdi but nothing to the coil.
