Rough idle, hard start, about 10 different codes thrown (low res pulse, etc etc). How many miles on the current opti?

i have no idea about the miles. It was never idling rough, or stumbling, or any symptoms. It jsut died while driving, and wont start. I have checked fuel pressure, so i, doubtful its the pump. So, im thinking opti. i need to try to scan it.
