[s-cars] S4 no start

[calvinlc at earthlink.net]

I agree with Mark. Or, just unplug the injectors and crank for awhile to
clear everything out.  Then try it again with the injectors plugged back in.
Don't forget you may want to clean your plugs after you get everything
cleaned out before you attempt the next firing.

Only other thing is could it be an ignition switch?

I don't think the ecu is the problem.
I would look to the intake sensor, with it at such a low reading it would be
the cause of the very rich mixture.

When any car that I have fails to catch, fires for a sec but does not run
on, then I will crank it and hold the throttle wide open. This will help
clear the fuel and should get the mixture to revert to default levels.

My guess would be a shorted or open sensor or wire somewhere.
