Using the fuel rail requires you to stay away from any combination of smoking and open flame alongside personal electronic devices near fuel-related components because of its highly flammable mixtures. First release fuel system pressure before disconnecting the battery ground cable. The right-hand side removal includes three steps: taking off the wiring harness retainer from the valve cover stud bolt and removing the three
Fuel Injector electrical connectors and then disconnecting the two fuel rail supply tube bolts which should be tightened to 6 Nm (53 lb-in) when reinstalled. Remove the old tube O-ring seal from the fuel rail supply while using 23 Nm (17 lb-ft) torque to fasten the right fuel rail with its two bolts. Launch the three fuel injectors from the fuel rail while discarding the O-ring seals keep special fuel-resistant material as a substitute. Discharge the fuel rail pressure and temperature sensor electrical connector and vacuum hose and radio capacitor electrical connector from the left-hand side. The two upper
Ignition Coil bracket bolts require a torque of 80 lb-in before reinstallation followed by tightening the M8 and M12 lower ignition coil bracket bolts to 18 lb-ft and 25 lb-ft torque specifications. After placing the ignition coil and bracket aside, detach the wiring harness retainer from the valve cover stud bolt and disconnect the three fuel injector electrical connectors and the two fuel rail supply tube bolts that need to be tightened to 6 Nm (53 lb-in) for reinstallation. Before continuing discard the old fuel rail supply tube O-ring seal then remove the two bolts retaining the left side fuel rail by tightening them to 23 Nm (17 lb-ft). Discard existing O-ring seals from the fuel injectors then install new fuel-resistant seals that will secure the fuel rail. The installation process completes when you follow the reverse order of removal steps and apply clean engine oil for lubricating the new O-ring seals prior to installation.
