Fuel Pump Wiring

I have a question:

On a 2002 Boxster S, where is the routing for the fuel pump, meaning where does the wiring from the pump enter the cabin? And does it go straight to the pump relay?

My car lost a lot of power, then quickly stalled and won't start. As it happened, it gave a few codes that said it was extremely lean.

I don't seem to hear the fuel pump come on when the key is turned, and I hooked up a fuel pressure gauge to the plug on the fuel rail, and it doesn't move the gauge at all. I know the relay is good, along with the fuse. I did the relay bypass recommended in the manual, and that didn't change anything.

So I am thinking that the fuel pump might have electrically went-out. I don't know if it could be a wiring problem, so I wanted to trace the wiring. I will probably remove the battery tomorrow, and seeing if it is getting power.

Any ideas?
Thanks,
