Hi, I'm Ron and I will be helping you today.Stand by for a moment while I prepare your answer.
O2 sensors won't keep it from starting. A totally plugged fuel filter can.
The problem can be a loss of spark or fuel. You can check forspark at the plugs with a spark tester.You can check fuel pressure with a gauge and both of these toolsshould be available to you at yourlocal parts store for rent or purchase.You need to check for any stored codes in the computer with acode reader or a scan tool.The code reader only gives the codes and definitions, where thescan tool gives you allthe needed data to diagnose the codes.
That code is an EVAP leak, it still won't stop the car from running.
Please check what i suggested earlier.
