When the ignition module triggers the coil to spark, the rotor must be lined up exactly with the plug terminal for that cylinder.

Watch where the rotor is pointing as the spark snaps. I bet the rotor is incorrectly indexed on the shaft, wrong rotor, or similar issue. If the electronics are located incorrectly in the distributor housing (old breaker plate) the same result happens, the rotor is not pointing to a terminal when it fires. Let us know what you find.
