Porsche told me there´s a service action to substitute the HPFP.
Yesterday I called my dealer to book my first mantainance service and the tech told me there was a world wide service action to substitute the high pressure fuel pump and that my VIN was inclueded on this action. It´s not a recall, they will make it when you drop the car to make some service I believe. My car is MY 10 , I receive it in August 2009. Normaly one of the signs of a bad HPFP is longer cranks to start the engine, mine doesn´t do it but they will substitute anyways.
Check with your dealer if your 997.2 is included on this action.
