Location of fuel cutoff switch in a 2003 nissan 350z
There is no fuel cut off switch. The electric fuel pump only operates for a few seconds when the ignition is switched on and will only remain on when the engine has been started. If the engine is not started and the ignition is left on the computer will cut power to the pump.
If you want to cut all power to the fuel pump you have to remove the fuse for the pump or remove the relay that covers the power circuit to the fuel pump.
Gas is getting in my oil in a 350z Nissan. what should I check or could it be my computer telling injectors more gas]
You may have a faulty injector that fails to shut off and is constantly supplying fuel. During operation it may not be noticeable, but when you shut the car off, the injector will pour fuel into the empty cylinder until fuel pressure falls off. This fuel will leak down along the piston rings into the oil, contaminating it. This will eventually cause cylinder wall damage due to "washing", the fuel is removing the protective oil film on the cylinder wall. This will cause much more wear on each start-up. Have the injectors tested.
