Sounds like you got a short in a wire. Maybe a fuseible link. Try following the wires you just cut for the nutter. Maybe your ecu. :dontknow:

2 most common problems for your symptoms, check and make sure you have power and a good connection for the switched power to the coil and ign module and/or replace the ign module again. I used to have at least 3 of those ign modules in my jeep at all times when it had AMC power with the Ford ignition.
