Looks like you may have two issues:
1) Something, possibly an alarm relay, is breaking the electrical connection to the fuel pump. To diagnose this, you'll have to trace the circuit from the fusebox to the pump. For details on the wiring, see if my article helps: http://www.unitedbimmer.com/forums/t...placement.html
2) Are you sure the pump runs when you apply direct power? It may make noise, but it doesn't necessarily mean it's pumping fuel. Next, if the fuel isn't making it to the rail, then check the fuel pressure regulator. There is no alarm component that will cut off the actual fuel passage; this is done electrically, as mentioned above in #1.
