The various random outputs of your programming results, and noting that the engine doesn't always buzz / jerk when you attempt to program is telling me you have a contact issue someplace. Something that is notorious on Atlas engines is the contact strip the axle ends run in. Oils tend to leach out to that location and build up in the journal making an excellent insulator ! Pop off the bottom cover of the trucks, remove the side frames and wheel sets. Wipe the axle ends with a clean rag - you'll be surprised what comes off. Then use some round toothpicks to ream out the bronze journal bushings. Make sure they are clean.
If you have your engine tore down to do this step, it's also a good idea to solder the truck wires to that bronze strip as well. The same oils that leach out to the journals will also create an insulation between the wire as well. Those black plastic clips are a poor excuse for a good electrical connection.
