START, STOP, NOW CRANK BUT NO GO

2002 Pontiac Sunfire • 280,000 miles

My fiancée got into the car, she said it started then stopped. Now it will crank and crank but not start. New spark plugs, good battery, and new wires. When I crank it it will shake and shutter. It might be the fuel pump because I can usually hear it running when I turn the key on.

I would check the fuel pressure or have it checked. You do have spark?

I have rented an auto scanner from autozone. It returns with PO140 which is O2 sensor and PO171 "system to lean"

That won't make it not start. Clear the codes and if you would make sure you have spark and let me know what you find ok.
