      I have a 2000 Pontiac Firebird 3.8 v6 5speed. The middle coil pack won’t fire. I replaces the pack and the ignition module with no luck. Where does the signal come from to tell the module which coil pack to fire?

      The ignition module does all the deciding on which coil to fire. If you are certain there is no spark from either tower when the other is still connected, you should check your spark plugs and plug wires.
