If you're experiencing fuel-related problems, the issue isn't likely a pump that needs resetting but rather one of these:
* Fuel pump failure: This requires replacement. Symptoms include a car that won't start, sputtering, or loss of power.
* Fuel pump relay failure: This is a less expensive fix than replacing the pump. The relay acts as a switch. A faulty relay can prevent the pump from activating. This can usually be tested by swapping the relay with another (of the same amperage rating) to see if the problem follows the relay.
* Low fuel pressure: This could be due to a clogged fuel filter, a leak in the fuel lines, or a faulty fuel pressure regulator.
* Other electrical problems: A faulty crank position sensor, camshaft position sensor, or other electrical components can prevent the fuel pump from getting the signal to operate.
* Fuel pump fuse: A blown fuse can also prevent the fuel pump from functioning.
What to do instead of "resetting":
1. Check the fuel gauge: Make sure you actually have gas in the tank!
2. Check the fuel pump relay and fuse: Locate the relay and fuse for the fuel pump in your owner's manual or online (many repair manuals are available). Visually inspect them for damage. A blown fuse will have a broken filament.
3. Listen for the fuel pump: When you turn the ignition key to the "on" position (but don't start the engine), you should hear a brief hum from the fuel pump. If you don't, the pump or its relay might be faulty.
4. Have a professional diagnose the problem: If you're not comfortable checking the relay and fuse, or if the pump doesn't prime, take your Malibu to a qualified mechanic for diagnosis and repair. They have the tools to test fuel pressure and pinpoint the actual problem.
Trying to "reset" a fuel pump when it's actually faulty will not solve the underlying issue. Focus on troubleshooting the possible causes mentioned above instead.
