OK, here's the scoop so far. I soldered together a second teensynet, and a teensypi. I followed the trouble shooting steps above. Everything is going well until I put a temp sensor in the action board. Nothing found. I then un-jumpered and wired the action board into the teensypi (with 3v3 lines), it all works. I am at a loss. I have yet to get the LCD working. Any thoughts?
