Interesting ur-quattro problem

Phil,

The car was towed with the ignition switched on and no fuses or relays 
removed.  Yes, I would have pulled fuse 13 or the fuel pump relay.  But
the 
system should still not have flooded the engine unless something is
wrong - 
like bad control pressure or leaky injectors.  But _gallons_ in a
ten-minute 
tow?

By any chance does this car have a DT (detections techniques)
chip(really
an ECU) upgrade? Way back, on some DT promo material I have, Peter W. 
stated that on some installs it was necessary to run the fuel pump all
the time, 
so the engine wouldn't cut it out. Can't remember exactly how they did
it, 
4000(80) fuel pump relay, hard grounded the orig ur-q relay, or internal
to the
ECU. Anyways, I seem to recall this as one reason I never pursued the DT
upgrade path.

If the above isn't the case, I think someone along the way hard wired
the fuel pump
on with the ignition switch. I would say a journey into the fuse box and
electrics
is in order.

HTH.
