For fuel pump removal, start by relieving the fuel system pressure and disconnecting the battery cable. Remove the rear seat cushion, then carefully pry up the fuel pump module/Fuel Level Sensor access cover. Disconnect the electrical connector(s) and fuel line from the top of the fuel pump unit, using a small screwdriver to release the yellow clip on the fuel line. Remove the retaining bolts of the fuel pump module/Fuel Level Sensor and carefully withdraw it from the fuel tank. If dealing with a Fuel Level Sensor, disconnect its electrical connector and slide it out after releasing the plastic locking tab. For fuel pump module removal on four-cylinder models (2011 and earlier), disconnect the fuel pump electrical connector from the fuel suction plate. Use needle-nose pliers to remove the spring E-clip, disengage suction support mounting clips, and separate the band bracket from the fuel filter assembly. Do not disconnect the fuel tube line between the suction plate and top plate to avoid damage. Remove the spring, disengage clips from the fuel suction support, and separate the support from the fuel pump. Pull out the fuel pump from the filter assembly, disconnect and remove the fuel pump electrical harness, disengage the clips securing the inlet strainer to the pump, and inspect the strainer for contamination. On V6 models and 2012 and later 4-cylinder models, pry the sub-tank from the assembly, remove the rubber cushion, disconnect the fuel pump electrical connector, disengage the fuel suction plate mounting clips, disconnect and remove the fuel pump electrical harness, pull the fuel pump out from the filter assembly, remove the clip securing the inlet strainer, and inspect it for contamination. For installation, reassemble the fuel pump module in reverse order and install the fuel pump/sending unit assembly in the tank, connecting the fuel line and electrical connector. Finish the installation as outlined in the removal process.
