The O2 (Oxygen Sensor) has nothing to do with the engine not starting. If it will not start you either have no spark or no fuel. If the engine will not turn over, it is either the starter, battery, connections, ignition switch, or starter solenoid. Some starters have the solenoid built into the starter. Test the battery, and all connections. Remove the starter and have it tested at any auto parts store.
What else can I help you with?
