Remove the engine covers. Relieve the fuel system pressure. Disconnect the cable from the negative battery terminal. Remove the intake manifold and the fuel pump/fuel rail insulator. The fuel rail fuel pressure sensor is located at the rear of the left-side fuel rail. Disconnect the fuel pressure sensor electrical connector. Unscrew and remove the sensor from the end of the fuel rail. Clean the threads in the fuel rail of any gasoline. Apply a single drop of oil on the new sensor threads, then install the sensor and hand tighten it. Remove the sensor, apply another drop of clean engine oil on the threads, then reinstall the sensor and tighten it. Connect the sensor electrical connector. The remaining installation steps are the reverse of the removal process. Remove the low-pressure fuel feed line bracket bolt and disconnect the feed line at the pump. Using a flare-nut wrench, unscrew the high-pressure line fittings between the fuel rail and fuel pump and discard the pipe as a new one must be used. Disconnect the electrical connector from the high-pressure fuel pump. Remove the high-pressure fuel pump bolts, then remove the cover, pump, and gasket. Always replace the bolts and pump gasket with new ones. With the pump removed, rotate the engine by hand and ensure that the camshaft lobe is at its base circle (lowest point) before attempting to install the pump. Lubricate the pump roller with engine oil. Using a NEW gasket, position the pump and cover onto the valley cover and tighten the bolts evenly, one turn at a time, from side to side. Tighten the bolts. The remaining installation steps are the reverse of the removal process. Clean the high-pressure fuel line fittings on the pump and crossover pipe, then apply a drop of clean engine oil to the threads of each fitting. Install the NEW high-pressure fuel line, tightening the fittings to the torque specified in the Specifications. The remaining installation steps are the reverse of the removal procedure. Reconnect the cable to the negative battery terminal, then start the engine and check for fuel leaks.

Remove the fuel filler cap and have an assistant turn the ignition switch to ON while you listen for the sound.
