  Q: How to check the fuel pump in Chevrolet Express?

  A: The fuel pump is located inside the fuel tank, making it difficult to hear when the engine is running. To perform a pressure check, use a fuel pressure gauge with a hose and an adapter suitable for connecting it to the test port on the fuel feed line. Start the engine and check the pressure on the gauge and if the pressure is not within specifications, you should check for obstructions in the fuel return line.

  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.
