As I understand it, the number 1 engine never started because it was never
given the command to fire. The start sequence is 3, then 2, then 1.
After starting engine 2, the onboard computers checked the valve state
on engine 3 and found the indication(s) that called for an abort.
The engine shutdowns were then commanded before the sequence proceeded
to start engine number 1.
