  Q: How do you remove the fuel pump/fuel level sending unit module for Chevrolet Cobalt,HHR and Saturn ION?

  A: To remove the fuel pump/Fuel Level Sensor, start by disconnecting the cable from the negative battery terminal. Then, relieve the system fuel pressure and equalize tank pressure by removing the fuel filler cap. Next, remove the Fuel Tank and disconnect the fuel supply and return lines from the fuel pump/Fuel Level Sensor module, being careful to soak up any spilled fuel. Mark the orientation of the fuel pump in relation to the fuel tank for proper realignment during installation. Use water pump pliers to unscrew the locknut counterclockwise, or use a hammer and brass punch if it's tight. Remove the fuel pump/Fuel Level Sensor, taking care not to damage the fuel inlet strainer or the Fuel Level Sensor float arm and float. For installation, inspect and replace the pump-to-tank seal if necessary, and ensure the fuel pump inlet strainer is clean. Carefully align and insert the fuel pump/Fuel Level Sensor module into the tank, avoiding damage to the strainer, float arm, or float. Finally, reconnect the battery and allow the Powertrain Control Module (PCM) to relearn its former driveability and performance characteristics.

  Q: How to check the fuel pump operation and fuel pressure?

  A: The fuel pump operation check involves listening for the soft whirring sound made by the fuel pump when the ignition key is turned ON. If the pump does not come on, check the fuel pump fuse, relay, and wiring. If they are all okay, the fuel pump is likely defective. Connect a gauge to the test port on the Fuel Rail. Relieve the fuel pressure, start the engine, and note the reading. The reading should be compared with the proper pressure specifications. If the pressure is not within specifications, the fuel system should be checked for restrictions and the fuel pump module may need to be replaced. Verify that the fuel pressure does not lose more than 8 psi for five minutes after the engine is turned off and to check for any fuel leaks.

  Q: How do you remove the high-pressure fuel pump for Chevrolet Cobalt,HHR and Saturn ION?

  A: To remove the high-pressure fuel pump, start by relieving the fuel system pressure and disconnecting the electrical connector. Then, disconnect the intake air ducting and remove the charge air cooler inlet pipe for better access. Loosen the fuel line fitting at the injector rail and the inlet/outlet lines at the high-pressure pump. Remove the bracket and fiber pump cover by removing the three bolts. Disconnect the flexible fuel line and remove the metal fuel lines from the high-pressure pump. Finally, remove the old fuel pump mounting bolts and discard them, replacing them with new ones. To install the pump, simply reverse the removal steps. Once everything is in place, start the engine and check for any fuel leaks.
