The ignition module fires the coil when pin 5 goes from 12V to 0V. The strobe signal from the Hall sensor goes first to the ignition advance computer and then to the ignition module. If the new coil does not give you sparks then check the grounds at the module.
I spent some time experimenting with ignition modules. There are several versions that look the same but have different characteristics and a couple that I bought new on Ebay were DOA.

Great idea to replace the starter while the engine is out of the car as it is not a fun job with the engine installed.

I have a good module and ignition computer that you can borrow if you have to resort to swapping them out.
