GMC 13516496 Sensor Assembly, Fuel Pressure

To replace the fuel pressure sensor, relieve the fuel system pressure, lift the vehicle onto jackstands, and disconnect the sensor's electrical connector. Unscrew the old sensor, discard its o-ring, and fit a new oiled o-ring onto the new sensor. Reinstall in reverse order, ensuring the sensor is tight. Before lowering, test for leaks by toggling the ignition switch to ON for two seconds, OFF for ten seconds, and back to ON, checking for any leaks around the sensor. For the fuel pump driver module, elevate the vehicle, disconnect its electrical connector, remove three mounting bolts, and extract the module. Reverse the process to install.

In order to take off the Fuel Pressure Sensor, first, remove the oil filler cap and engine cover fasteners. Then, lift the engine cover along with the valve cover insulator off of the valve cover and reinstall oil filler cap. Next, relieve the fuel system pressure and disconnect cable from negative battery remote terminal. Finally, disconnect the Fuel Pressure Sensor electrical connector and unscrew and remove it from the fuel rail. Clean thread in fuel rail and put a drop of oil on new sensor threads before installing it. Remove sensor again, apply another drop of clean engine oil on threads then reinstall it. Connect the sensor electrical connector and reverse removal process. To remove high-pressure fuel pump, start by removing charge air cooler outlet hose. Disconnect harness connector to the fuel rail and harness connector from camshaft position sensor. Unclip wiring harness retainers then move them out of way of harness and connectors. Remove sound insulator around pump body. Unscrew intermediate high-pressure line fittings between fuel rail and fuel pump; remove bracket bolt for this line as well as for those that hold wiring harnesses for low-pressure feedline disconnection at high pressure electrical component(s). So now, we have removed low-pressure feed line too! Get rid of high-pressure fuel pump bolts removing pump itself also gasket or lifter follower (if any). Lifter follower must be lubricated using clean engine oil before being installed into bore on cylinder head so where does that leave us, Put alignment gauge in place rotate motor until gauge is level with top side of cylinder head now take out alignment gauge if necessary pull up on valve lifter follower insert it into bore lubricate it with some engine oil let's get things done here people! Just tighten bolts evenly using new O-ring gasket to secure pump position bore; thus completing remainder installation procedures which are carried out exactly opposite order since The Rest Is Reverse Of Removal Process in this case, Reconnect the cable to the negative battery remote terminal, start the engine and check for fuel leaks.

Disconnect the cable from the negative battery terminal and remove the engine cover. Relieve the fuel system pressure and wait at least two hours before proceeding. Remove the intake manifold and remove the foam insulator. Disconnect the electrical connector from the sensor and unscrew the sensor from the fuel rail. Installation is the reverse of removal. Tighten the sensor to the torque.

Next, relieve the fuel system pressure and wait for at least two hours before proceeding.

Raise the vehicle and support it securely on jackstands. Remove the fuel tank. Disconnect the electrical connector from the canister vent solenoid valve. Disconnect the hoses from the canister, which is located on top of the fuel tank, at the rear. Remove the retainer securing the canister on top of the fuel tank and remove the canister.

After removing the intake manifold, you should disconnect the electrical connector from the sensor(s).

Remove the fuel tank filler cap.

The fuel pump flow control module (FPFCM), also referred to as the Fuel Pump Power Control Module, is located under the model, above the spare tire.

Accessing and replacing the EVAP canister and fuel tank pressure sensor requires raising the vehicle and securely supporting it on jackstands.

Before installing the high-pressure fuel pump, you should ensure that the camshaft lobe is at its base circle (lowest point) and lubricate the pump roller with engine oil.

V6 engines for 2012 and later model have the fuel pressure sensor either mounted on a hitting on the fuel tank or directly on the fuel tank with no hitting.

Disconnect the electrical connector from the fuel pressure sensor.

After removing the engine covers, you should remove the intake manifold and the fuel pump/fuel rail insulator.

Slide the solenoid from its mounting tab, and installation is the reverse of removal.

The new O-ring should be coated in clean engine oil before installation.

To remove the EVAP canister, raise the vehicle securely on jackstands, remove the fuel tank, disconnect the electrical connector and hoses from the canister, and use a screwdriver to pry the canister upwards from the fuel tank. Installation is the reverse of removal.

For installation, simply reverse the removal steps and tighten the sensor to the specified torque.

You should tighten the fuel pressure sensor securely.

Installation is the reverse of removal.

To remove the fuel pressure sensor from the fuel supply line, you need to unscrew it.

After raising the vehicle on jackstands, you should disconnect the electrical connector.

Raise the vehicle and support it securely on jackstands. Remove the fuel tank. Disconnect the electrical connector from the canister vent solenoid valve. Disconnect the hoses from the canister, which is located on top of the fuel tank, at the rear. Remove the retainer securing the canister on top of the fuel tank and remove the canister.

Start by disconnecting the cable from the negative battery terminal and removing the engine cover.

The first step is to relieve the system fuel pressure and raise the vehicle on jackstands.

To replace the fuel pump flow control module, you need to disconnect the electrical connector and remove the three mounting bolts before removing the module from its bracket.
