[s-cars] S4 no start

[Mark Strangways]

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.
