I did find this on a Mazda forum: "TCM Error: TCM U0100, RAW: C100, Meaning: Lost Communication With ECM / PCM A" but none of my other information gives any information on this code.

If you do not properly warm up the 2004 rotary engine in this car ( and I mean actually driving it) until proper driving temp, it will flood. Happened to me 2 times within 3 months. The first time I didn't know better and just let it idle to warm. 2nd time my friend was convinced he could move it from outside the garage to inside the garage in a snowstorm. The second time around, I learned how to deflood my own engine b/c repairs are about $700-800 :-( to basically replace 4 spark plugs.
