No Start, 1993 100CSQ Avant Auto

[LL - NY]

Trying to diagnose the above vehicle without the aid of a 
Bentley's or VAG-COM (both rather packed away in storage,
helping out a friend). 

Symptoms: Car starts briefly, runs for about 15 seconds, then
slowly stalls. Will not restart. My hearing sucks, so I can't
tell if fuel pump is running, but it acts like there is no fuel. Car
cranks fine. Fuel pump fuse is fine (even swapped one to be sure)
Car does have about 198 k miles on it and has been reasonably 
maintained. 

Several questions:

Does the car use a Fuel Pump Relay? I searched the underhood
relay box and the drivers footwell area and found none.

If it does use a relay, what pins would need to be shorted in order
to get the pump to run full time?

Other than that, any other suggestions?

TIA,
