Ok sounds like its doing something. I'm not sure what order you are doing this.
With the engine running put the 10k across A/B remove it and plug in the red Devil.

If you turn the ign off this will reset every thing. You may not see the cel light flash, I've got a LED and its very bright, they are not always the same.
It sounds like you forced the data to stream. You have to see why it does not start the normal way.

Note if you start this with the IGN on and then start the truck, this will possibly rest again. Depending on the wiring configuration the power on the ALDL plug can flash off when you hit the starter.
