Need to load firmware on the JB4 or remove it all together. Won't run if installed with no firmware loaded. If it times out just keep trying. Ensure ignition is on properly.

2abc errors will cause 3100 errors and no boost. If you have an upgraded tmap and remove the JB4, make sure to swap the stock sensor back in.
