You've verified that you're getting +12V on one side of the coil primary. It's the ignition module's job to open and close the connection to ground on the other side of the coil's primary. So, here's what you do: take a 3357 light bulb, or any other 12V light bulb with wires for connectors, and splay them out, connecting across the coil connector. When you crank the engine, that light bulb should flash rapidly. If not, you've either got problems with the ignition module, EEC relay/power, or a PIP (hall effect switch/pickup) signal isn't being sent to it.

You've already changed the ignition module (with a KNOWN and TESTED good one, right???), so you should start checking the module's connector and the hall effect switch in the distributor bowl. The Haynes manual has the pinout and voltage/resistance checks for the connectors laid out nicely. When you installed the new module, did you look up into the hall effect switch to see if the terminals were okay? Sometimes those get loose and cruddy; I had one on an '85 four-banger melt on me once, and ended up replacing the distributor.
