What you might be experiencing are symptoms that *seem* like the fuel pump needs resetting, but actually indicate a different issue. Possible problems and troubleshooting steps include:
* Fuel pump relay: This electrical component might be failing or stuck. Check the relay (location varies by model; consult your owner's manual). You can try swapping it with a known good relay of the same type to see if that solves the problem.
* Fuel pump fuse: Similar to the relay, a blown fuse will prevent the pump from operating. Check your fuse box (again, your owner's manual will show you the location and fuse ratings).
* Low fuel pressure: This could be due to a failing fuel pump, clogged fuel filter, or other fuel system issues. A mechanic will need to check fuel pressure using a gauge to determine if the pump is delivering the correct pressure.
* Clogged fuel filter: A dirty fuel filter restricts fuel flow, mimicking a weak pump. Replacing the filter is relatively inexpensive and easy.
* Fuel pump itself: The pump might be failing due to age, wear, or debris. This requires pump replacement – a more involved repair.
* PCM (Powertrain Control Module) issues: The PCM controls the fuel pump. Problems with the PCM could prevent the pump from activating, but this is less common and requires professional diagnosis.
In short: If you're having fuel delivery problems, don't try to "reset" the fuel pump. Instead, consult your owner's manual, check fuses and relays, and consider taking your Malibu to a qualified mechanic for diagnosis and repair. They have the tools and expertise to identify the true cause of the problem.
