The starter motor cranks the motor over, or the starter motor doesn't even engage, or it just clicks?
....went to start, all the usual dash self check lights come on, turn to the start, and no start....
....I did notice when all the lights went out, the engine and some sort of Zorro lightning bolt stayed lit, and of course the oil light, engine light flashed a few times on one attempt....
All that sounds normal, all the dash warning/advisory lights come on for a second as a self test, if the motor does NOT start, then the lights that would stay on or the one you'd get for ignition on with a stalled motor.
The Zorro Lightning Bolt warning light is actually the Throttle Control Warning Light, something is wrong with the drive by wire, or it might be normal for a motor that won't start.
BUT, the Check Engine Light (CEL) flashing is a clue. If the CEL lights and stays lit, it means you have a problem that needs to be repaired, you won't damage the motor if you continue to drive a while with the problem. If the CEL flashes, it means you have a serious problem that might damage the motor if you continue to drive while its flashing. But again, this might have been induced by trying to start a motor that won't start.
Did you do the key dance and get the EVIC to spit out the stored fault codes? That would likely tell you the problem.
If the starter would NOT crank the motor over, it could very well be just the battery. NOT uncommon for it to act like this at the end of its life, provide enough current to make the vehicle act normal, but when you put a big load on it like the starter, it just dies out.
