  Q: How do you remove the fuel pump/fuel level sensor module?

  A: To remove the fuel pump/fuel level sending unit module, start by relieving the system fuel pressure and disconnecting the negative battery terminal. Then, remove the Fuel Tank and disconnect the fuel supply line, being careful to soak up any spilled fuel. Mark the orientation of the fuel pump for correct realignment during installation. Use water pump pliers to unscrew the locknut, and if necessary, loosen it with a hammer and brass punch. Raise the pump assembly to disconnect the quick-connect fitting for the ventilation harness, and remove the pump assembly without damaging the fuel inlet strainer or the fuel level sensor float arm and float. For installation, inspect the O-ring and fuel pump inlet strainer, replacing if necessary. Insert the fuel pump assembly into the tank, connecting the ventilation hose before locking it into place. Take care not to damage the fuel inlet strainer, float arm, or float. Ensure the float arm is not bent to maintain accurate fuel level indication. Finally, reverse the removal steps for installation.

  Q: How to check the Fuel Pump for Pontiac G6?

  A: To check the fuel pump, listen for soft whirring when the ignition key is turned ON. If the pump does not come on, the fuel pump fuse, relay, and wiring should be checked. If they are okay, the fuel pump is likely defective. To measure, connect the fuel pressure gauge to the Schrader valve-type test port on the fuel feed line. Compare it to the specified pressure. If the pressure is lower, a restricted fuel filter or supply side fuel lines and hoses should be checked. If the pressure is still low, the regulator might be stuck open or the fuel pump could be clogged or defective. If higher, the fuel pressure regulator might be stuck closed. After the fuel pressure check, the engine should be turned off and the fuel pressure should not lose more than 5 psi for five minutes. Finally, any fuel leaks should be checked for.
