The fuel pressure sensor can be found just above the fuel rail lines which are mostly in front of the engine on most models. Depressurizing the fuel system is a must before removal and can be done by starting the engine and removing the fuse for the fuel pump. Ignition needs to be turned on and off a couple times after installation of the new fuel sensor to pressurize fuel circulation before starting the engine.
