Check for a burned fusible link under the hood. If you have power at the fuel pump relay, you could have a bad ignition switch or bad oil pressure switch...accordianman

SOURCE: fuel pump relay
Located under the steering wheel. The fuse should be #28 and the relay will have 167 or 409 on it. Here is a link to a wire diagram for the TT

Check your ecm relay I had one go goofy on my 1994 Passat it controls power to the ecm modual the car will turn over but will not start it should read 109 on the top of the relay I replaced it in my passat and it fired right up and I havent had a problem since

I would definately check the fuel pump relay, should be located in power distribution box in your vehicle, you may be able to switch it out with a relay of the same type to see if it turns on the fuel pump, but you may need a new fuel pump if this doesn't fix it. Hope this helps.

I have a question. Turn the ignition on you should hear the pump for about 3 seconds. then it should stop. this is normal operation. then when a signal is sent to the ignition that you are going to crank it then it switches on. I can see how this can seem like the pump is not working but after you crank it you should be able to hear the pump for about 1-1.5 seconds after the crank then it will stop. The pump will not turn on until it is told to do so by the computer.
