Once you have everything replaced again, give it a try. If still no joy, start braking the connections "one" at a time checking for voltage at those connections. Let us know the locations where you have votage and no voltage, so we can troubleshoot with you. You said you have power at the coil, but not going to the distrubutor from the mod?? Can you get your hands on a spare mod? (even if yours is new) or brake the pigtail distributor connection, are you getting a reading there from the mod?
PS, Your not "at" a complete loss......because there's just no giving up. (MOPAR DISIPLINE)
