How to remove and install the high-pressure fuel pump for Cadillac CTS?

This procedure applies to 2008 and later 3.6L (except VIN 7) and all 3.0L V6 engines. Remove the engine covers and the suspension crossbrace. Relieve the fuel system pressure and disconnect the cable from the negative battery terminal. Remove the cowl panel and the wiper motor and linkage. Remove the high-pressure fuel pump line shield fasteners and shield. If necessary for additional working space, remove the intake manifold and both fuel rails. Disconnect the low-pressure feed line to the pump. Using a flare-nut wrench, unscrew the high-pressure line fittings. Disconnect the electrical connector from the high-pressure fuel pump. Remove the high-pressure fuel pump bolts and remove the pump. Always replace the bolts and O-ring. With the pump removed, rotate the engine by hand and make sure the camshaft lobe is at its base circle before trying to install the pump. Lubricate the pump roller with engine oil and install the gasket and bolts. Set the pump into the cylinder head and tighten the bolts evenly. As the pump bolts are tightened, it will get harder to tighten the bolts until the spring in the pump is compressed. Tighten the bolts. The remainder of the installation is the reverse of removal. Clean the high-pressure fuel line fittings on the fuel rails, then apply a little clean engine oil to the threads. Install the new high-pressure fuel line, tightening the fittings. Reconnect the cable to the negative battery terminal, then start the engine and check for fuel leaks.

How to remove and install a fuel pump module for Cadillac CTS?

There are two fuel pump modules. The primary module includes the fuel pump, a fuel level sending unit, a fuel filter and, on mechanical returnless pumps, a fuel pressure regulator. The secondary module includes a fuel level sending unit and the fuel pick up. On electronic returnless pumps, there is no regulator; fuel pressure is regulated by a Fuel Pump Flow Control Module (FPFCM). None of these components are separately serviceable. First, relieve the fuel system pressure. Disconnect the cable from the negative battery terminal. Then, remove the fuel tank. Disconnect the electrical connector and the fuel supply line quick-connect fitting from the fuel pump module. Using pliers against the locking ring and the module, rotate the lock ring counterclockwise to remove it. Carefully pull the fuel pump module out of the tank and disconnect the transfer tube that connects the modules. Angle it as necessary to protect the fuel level sensor float arm and remove it from the tank. Inspect the O-ring and replace it if it shows any sign of deterioration. Installation is the reverse of removal. On vehicles equipped with an electronic returnless fuel system, the fuel pump module speed, and therefore the output and pressure, is controlled by the FPFCM, which is located in the left rear part of the trunk/luggage compartment. On sedan and coupe models, remove the carpet trim from the left rear part of the trunk. On wagon models, remove the rear floor storage compartment. Disconnect the electrical connector from the FPFCM. Remove the pin-type retainers and remove the FPFCM. Installation is the reverse of removal.

Q: How to remove and install the high-pressure fuel pump for Cadillac CTS?
A: This procedure applies to 2008 and later 3.6L (except VIN 7) and all 3.0L V6 engines. Remove the engine covers and the suspension crossbrace. Relieve the fuel system pressure and disconnect the cable from the negative battery terminal. Remove the cowl panel and the wiper motor and linkage. Remove the high-pressure fuel pump line shield fasteners and shield. If necessary for additional working space, remove the intake manifold and both Fuel Rails. Disconnect the low-pressure feed line to the pump. Using a flare-nut wrench, unscrew the high-pressure line fittings. Disconnect the electrical connector from the high-pressure fuel pump. Remove the high-pressure fuel pump bolts and remove the pump. Always replace the bolts and O-ring. With the pump removed, rotate the engine by hand and make sure the camshaft lobe is at its base circle before trying to install the pump. Lubricate the pump roller with engine oil and install the gasket and bolts. Set the pump into the cylinder head and tighten the bolts evenly. As the pump bolts are tightened, it will get harder to tighten the bolts until the spring in the pump is compressed. Tighten the bolts. The remainder of the installation is the reverse of removal. Clean the high-pressure fuel line fittings on the fuel rails, then apply a little clean engine oil to the threads. Install the new high-pressure fuel line, tightening the fittings. Reconnect the cable to the negative battery terminal, then start the engine and check for fuel leaks.
