my mate has the same problem with his quattro, which just had a new GTi tuned engine. The problem can still be the pump, but not its not working at all, but the wiring. His problem is that the fuel pump primes when the ignition is turned on, so there is fuel to start the car, then when he turns it over it bursts into life and dies as the pump doesn't keep running when the end is running.

if you can, hardwire the fuel pump to a battery and when you start the car, connect it up and it should run fine.. if so its probably the relay thats given up. unfortunately not sure where they are in the car for the fuel pump circuit, im sure the Haynes Manual of Lies will tell you though.

Hope this helps mate :)
