Re: 1998 A4 Won't Start
Mike,
Crying helps? wow - maybe the tears are actuating the "Empathy Module"?
Hmmm....it sounds like something is overheating. Basically, you need gas
and a spark to make it run. My 1987 5ktq has behaved poorly with hot
starts, but not to the extent you describe. In the 5ktq case, it has a lot
to do with leaking injectors and vapour lock - as the exhaust manifold is
under the fuel lines, you can easily heat the fuel in the lines to the point
that they will vapour lock. The release of fuel pressure from the system,
whether from leaking injectors of from a leaky fuel check valve, may cause
difficult starting, especially if the injectors leak and flood the engine.
I would attempt to duplicate the failure mode at European Auto (I know,
it'll be tough to do because the car will "know" you're there), and then
check for fuel and spark. Then troubleshoot from there - check fuel
pressures if no fuel (also faulty fuel pump, leaking injectors, even a lack
of a signal from the computer to turn the fuel pump on - my 5ktq uses the
RPM sensor to make sure the car is running before turning the fuel pump on)
The A4 folks will tell you if the failure of the Mass Airflow Sensor or the
Oxygen sensor will throw codes - I suspect they would. If there's no spark,
I would look to the wires, coils (coilpack failure? they _never_ fail,
right???? - wrong) - computer? C'mon Ronny....a little help here.....
You might also try the A4 forum at Audiworld if you haven't already.

Does it actually turn over? My 98 A4 had something go ary last
year that when you turned the key, it was a crapshoot as to
whether or not anything would happen. The mechanic fixed it and
haven't had a problem since. SOme sensor or something. Sorry -
best I can do without digging up records and I'm not near those
right now.

Yes, it turns over, but does not start. My sister talked with the
people working on it, and they mentioned something about a sensor
sending too much fuel to the engine and flooding it immediately... does
that sound familiar at all?
