  Q: How to replace the fuel pressure sensor and remove the chassis control module on Chevrolet Express?

  A: To replace the fuel pressure sensor, start by relieving the system fuel pressure. Then, raise the vehicle and support it securely on jackstands. Disconnect the electrical connector from the fuel pressure sensor and unscrew it from the fuel supply line. Remove the old fuel pressure sensor O-ring and replace it with a new one coated in clean engine oil. Securely tighten the fuel pressure sensor. Before lowering the vehicle, test for leaks by turning the ignition switch key to the ON position for two seconds, then to the OFF position for ten seconds, and finally back to the ON position. Inspect the area around the fuel pressure sensor for leaks. To remove the fuel pump driver module, locate it under the vehicle mounted to the outside of the driver's side frame rail. Raise the front of the vehicle and support it securely on jackstands. Disconnect the electrical connector from the fuel pump driver module and remove the module from its mounting bracket by removing the nut. To install the fuel pump driver module, simply reverse the removal process.

  Q: How to remove and install the engine covers, fuel rail fuel pressure sensor, and high-pressure fuel pump for Chevrolet Express?

  A: To remove the engine covers, relieve the fuel system pressure, and disconnect the cable from the negative battery terminal. Then, remove the intake manifold and the fuel pump/fuel rail insulator. For the fuel rail fuel pressure sensor, disconnect the electrical connector and unscrew the sensor from the end of the fuel rail. Clean the threads and apply oil to the new sensor before installing it. Tighten the sensor to the proper torque specifications and reconnect the electrical connector. The installation process is the reverse of removal. To remove the high-pressure fuel pump, disconnect the low-pressure feed line and unscrew the high-pressure line fittings. Disconnect the electrical connector and remove the pump bolts, cover, and gasket. Replace the bolts and gasket with new ones. Ensure the camshaft lobe is at its base circle before installing the pump and lubricate the pump roller with engine oil. The installation process is the reverse of removal. Clean the high-pressure fuel line fittings, apply oil to the threads, and install the new high-pressure fuel line. Finally, reconnect the cable to the negative battery terminal, start the engine, and check for fuel leaks.
