Barracuda woes :(

I think you should listen to what you are saying. You said the last thing you did was to zip tie those wires together.Take them apart, unwrap them and look for breaks in the wire insulation. It could be that coil is not compatible with your system. I had several Mallory coils go bad on me.(no I didn't keep buying them,they came on the cars). You said the spark was very weak. Try another coil, also do what 67Dart273 says whether it's this or another problem,cause then you know everything is functioning correctly.
