Will, Just to be clear, you have ascertained spark,air and fuel? You say the motor cranks so it appears your battery and starter are OK.Are all your sensor connections tight,clean etc? I like to make sure I've ruled out the most obvious before going to a dealer. My guess about the o2 code is it was stored in memory and has been there before this problem and shouldn't have any affect on starting anyway. But i may be wrong. If your getting air,spark and fuel my next step would be timing barring any sensor malfunctions.Good luck at any rate and let us know what it turns out to be.
