I have weak spark. Pink, not nice hot blue spark. My timing light will pick up spark on my coil wire, but not on any plug wires. This doesn't make any sense. Only place for that wire to find ground is through a spark plug, so how could I possibly lose so much power through the cap and rotor?

Replaced so far: cap, rotor, points, condenser, plug wires, coil. Had 1 new plug in there and no change.

I'm working in a tent so I can't even bang my head against the wall.

Grounds are as follows:
Battery to bell housing 4ga
Transmission to frame 1ga strap
Block bolted directly to frame
Battery to frame 14ga
Battery to engine (coil bracket) 14ga

I might try moving the bell housing ground to something on the block, maybe the motor mount bolt...

I really can't think of anything to make this more grounded but I'm all ears!

Pull the cap crank the engine see if the rotor is actually spinning, I fought a bunch of stupid issues on a kids mustang this summer, the dowel pin that holds the distributor gear on had broken

Possible you have the wrong cap or rotor and the gap is too big? Do you have a hot spark if you check out with the coil wire?

Voltages, what are your voltages? Battery voltage at coil + during cranking. Voltage at coil - should be battery voltage with points open and 0 with points closed.
