the switch in the trunk is the inertia switch, used to deactivate the fuel pump in the event of a crash. to depressureize the fuel system, you have to depress the valve on the fuel rail.

you can also do it by unplugging the inertia switch all together and then starting the car and running it out of gas

It is right by #1 spark plug on the feul line. Let the car set (without running) for a while the pressure will go down.
