You don't even need to touch the shut off relay, besides, that is in the event of a wreck. If inertia is applied in force, it triggers the switch to turn off fuel. Once the ignition is off, bleead the pressure out by depressing the tire like valve on the fuel rail. Change the filter and then turning the key on will repressurize it.
Good Luck

After you shut off the car, lift the hood. On the fuel rail assembly where the injectors come from and you should find a valve that looks like a valve stem you see in a tire. Press the steel relief pin in the middle of it in and gasoline will squirt out and relieve the pressure.
It's called a pressure relief valve. The best way to relieve it is to place an old rag over while you push the pin in.
You're going to have some gasoline run out of the fuel line when you take the old filter off anyway, so use a catch pan.
You don't need to fool with that safety shutoff switch. It's a safety device and if you trigger it manually it might fail in the event of an accident.
Finally, if you're going to work on your own cars, invest in the repair manual sold for that year make and model of car. The name of the manual is Hayne's or Chilton's. Hayne's manuals are better. They tell you step by step how to properly make repairs just like this one, and much more.
They cost about twenty dollars but they are a wise investment.
Good luck

The fuel shut off disables the pump in the event of an accident you need not fool with this for a filter replacement. If you want to release the pressure, just go to the schrader valve on the fuel injector rail. It looks like an air valve. Wrap it with alarge cloth and take a small screw driver and push in the valve core. Alot of pressure there so keep your face out of the way.

That switch in the trunk is called your inertia switch it shuts off the fuel in the event of a collision get a repair manual and you should be able to find a fuse or relay to remove that will let you relieve the fuel pressure

I don't think you have the tools to replace it yourself.
