Valve timing - make sure your chain didn't jump, which would explain your compression (other than wear, obviously), if the valves are opening at the wrong time. Or, do you have reference compression for this motor? Was it already 140?
Does the exhaust smell like fuel? Or pop if you crank a while? Does playing with the throttle do anything?
How did you check spark? Are you confident that it's sparking the same way while you crank?
No distributor control or crank angle sensor or similar type wires dragging on belts, or anything like that?
And, r3b, your ecu is fine, it's some combination of things you broke.
