[s-cars] Let's rally to help a fellow S-car owner in troubleshooting Hell in Wisconsin !

[Postupack, Jeff]

Brook needs the collective assist of  Tha List!

Read on:  I sold Brook a new CPS a while back. he thought that might
cure his no-start.  Here's today's story. 
 
Not running, but it tries to start/catch... ...I believe I verified that
the speed sensor pin is still on the flywheel.  I pulled the sensors
with the engine @ TDC and viewed a square pin through the opening.

This is the synopsis of my struggles:

*	With a half tank of fuel and driving the 95 S6 w/ 129K miles,
the engine hesitates/stumbles then dies.  It refires, but runs poorly
then dies. 
*	With the car back home, I swap the crank speed sensors from my
other S6 and still a no start condition. 
*	Compression is high of 135 and a low of 125 across the
cylinders. 
*	I swap out the old POS units with known to be working POS units
and still a no start condition. 
*	I swap out the old coils with a 034 ignition loom with 5 new
1.8t coils and still a no start condition. 
*	I by-passed the fuel pump relay to check the fuel pump function
and it appears to pump fine from the filter line (I did not measure the
exact volume or measure from the fuel pressure regulator or the
injectors)  I checked to make certain it was fuel, not fuel/water coming
from the tank. 
*	I spliced in a super groovy CPS purchased from a very patient AW
forum user and still a no start condition. 
*	I replace the fuel filter, spark plugs, crank seal, cam seal,
TB, serp belt, serp tensioner bearing, H2O pump, T-stat, triple checked
the timing marks but did not install the radiator and still a no start
condition.  (I have to return the Audi tools back to Force5 today) 

 

What other causes could it be?

*	Plugged cats 
*	Injectors 
*	Bad karma
