Hi Shane,

If I were in your shoes, I'd trust my sniffer. Rich does sound like the issue, although the explanations for those codes "rich or lean when..." are maddening, when we know the computer could have told us which.

What you can do now, while the no-start persists (or immediately after next time) is pull each of the spark plugs and check for fuel. Look at the color of the deposits on the insulator. Sniff the oil dipstick too. Notice whether it seems to be fuller than you expected. With the motor off, check for fuel in the fuel pressure regulator's vacuum line.

It will probably start once again, if you wait. Take a whiff at the tailpipe to see if it smells fuely rich. Then 80 miles to your mechanic only if you've made certain the excess gasoline is not dumping into your crankcase; otherwise change the oil immediately.
