Do you have a wiring diagram? There is a relay on the firewall that switches between the 2 pickups. Do away with it and make sure the wires for the pickup you are using wind up going to the ECU. Recheck the timing when you get it wired correctly. As for the spark being weak, how did you get the wires to reach the dist. on the 440? Double check the connections and the polarity.
Here's a diagram I had saved. Racer 413 is right, find and eliminate that relay and wire it for one pickup. Good luck!
