Disconnect the battery negative (-) cable in the cargo compartment, ensuring to read the battery disconnection cautions beforehand. Remove the cabin microfilter housing, followed by the ignition coil cover and ignition coils, while maintaining a high level of cleanliness to prevent fuel or oil residue from causing a breakdown of the electrical resistance qualities of silicone, which can lead to ignition coil failure. Label the position and remove high-pressure fuel lines by using the special tool to loosen the nut while holding the injector with a wrench. Maintain a clean work area to avoid contaminants that could cause system malfunctions, sealing all fuel system openings with protective caps and replacing high-pressure fuel lines if tightened ten times. Seal the injector with a cap and the fuel rail connection with a plug from the special tool kit, and seal the removed high-pressure fuel lines with caps. Unlock and remove the electrical connector from the fuel injector rail, as well as the electrical connector holders and the fuel rail pressure sensor electrical connector. While working at the fuel injector rail, loosen the fuel line nut, plug open fuel lines and fittings, and wrap a clean shop towel around the fitting before disconnecting due to residual fuel pressure. Finally, remove the fasteners and the fuel injector rail, sealing connections at the high-pressure line and fuel rail.
