Check all of your fuses first and foremost. Redundant, yes, but best to clear the easiest options first.
If the fuel pump is found to be fault, DO NOT replace it without replacing the sending unit as well - Porsche idiotically integrated the fuel filter into it in 2002.
I had this issue several years ago where I went through 2 brand new OE fuel pumps then discovered my filter was clogged. This, of course, was after having a no-start issue where it would crank (tach moved), but had no fuel at the rail. In that scenario I had also replaced the fuel pump relay.
