So we tried again to start this thing. (74 Challenger, Stockish 318, stock ignition) New ECU, wiring has been gone through ad nauseam. I got power at the + primary on the coil and power on the blue/yellow wire on the ecu both with key on run and key on start albeit, the voltage is only 4.8 on the primary + coil and slightly higher on the blue/yellow but assumed this is due to ballast. I get spark from the coil secondary by dragging zigzag connector across a ground and holding coil secondary cable 1/4" from a ground.

However, I got no spark at the spark plug (New rotor, cap and cables). I've triple checked gap at distributor pickup/reluctor. I'm thinking bad pick-up coil. Yes? No?

Thanks,
Scott
