Replaced the brain and that almost got it. Seemed to really want to start. Checked timing - 5 degrees retarded!! No more code 320 though. Reset TDC, belt, and cam sprockets again and again. Still same thing!! so frustrating. I got to thinking something has to be wrong with the crank position sensor. Pulled it out and the magnet was cracked in half!! don't know how it happened. Will get one tomorrow and see what else is bad!
