My car stopped running in my work's parking lot. I know it's the o2 sensor. I need instructions on where it is located and is it possible to replace the sensor while it is jacked up in a parking lot. Or is it to difficult to change due to the placement of the o2 sensor?

It isn't the oxygen sensor.
O2 sensors have no effect on the cars ability to start and run. If the heater circuit is compromised then there will be a blown fuse.

Dr. Hagerty is correct, it is most likely the crank sensor or you have a bad fuel pump check all fuses and relays.
