Modules will do a partial fire.

I did run a new wire after I had the same problem.

I carry a spare in the toolbox. I'll swap it in and try it.

I guess anything is possible but I've never had a module partially fire.

It's easy enough to check if all the wires are firing with a spare plug and clamp grounded to the engine. Or, a timing light clamped to the wire while cranking.

Also check for pin hole in rotor, loose crimps or loose electrical connections.
