My 2004 Boxster is doing the same today!
No sound coming from the fuel pump but also no Amps from fuel pump fuse (so my roadside cover person said)
Where should I start??
My problem turned out to be a weak "positive" ground in the engine compartment. It was rusty, and if I wiggled the cable and turned the key the engine would start. Disconnect the battery. It is located in a black plastic box next to the power steering reservoir. Use a screw driver to pop the box open and a 14 mm socket to remove and clean the nut.

I'm going to save your pictures.
I can't tell you how many times I've tried to explain to people exactly what and where this distribution block is and the issue it causes when that nut loosens...I always forget to get a picture when I'm in the engine bay.
