beerman makes a good point. Everything is there to create a spark but the ignitor is not making and breaking the circuit.

Re-read thread and it seems like your coil negative post is grounded all the time. You either have too many wires connected to the negative post or you have a short to ground on the wire to the negative post or the module is damaged. That would explain all of the symptoms, except maybe the spark when the key is turned on. I would focus on the wire to the negative post and any place that it goes.

Still trying to figure out the correct wiring to get a consistent spark. Dont know why the ac shop threw a wire from the coil to the ac blower?

Because it was an easy place to get switched power and they're not a very good mechanic..
