* Bad fuel pump: This is a common failure point and requires replacement.
* Blown fuel pump relay: This is a small, inexpensive part that can be replaced.
* Faulty fuel pump inertia switch: This safety device cuts power to the pump in a collision and needs to be reset (usually involves pushing a button, often located in the passenger compartment, usually under the dash or in the trunk). This is the closest thing to a "reset" button you'll find related to the fuel system.
* Low fuel: Make sure you have enough gas!
* Electrical problem: A short circuit or other electrical issue could prevent the pump from getting power. This requires diagnosing the electrical system.
* Clogged fuel filter: Restricting fuel flow.
To troubleshoot:
1. Check the fuel level: The most obvious first step.
2. Locate and check the inertia switch: This is the most likely candidate for a "reset" action. Consult your owner's manual for its location.
3. Listen for the fuel pump: When you turn the ignition key to the "on" position (don't crank the engine), you should hear a brief hum from the fuel pump. If you don't hear it, the pump or relay might be the problem.
4. Check the fuel pump relay: Find the relay (your owner's manual or an online repair manual will tell you its location and appearance). Try swapping it with another relay of the same type (if possible, to rule out a bad relay).
If you're not comfortable working on your car's fuel system, it's best to take it to a qualified mechanic for diagnosis and repair. Working with fuel systems involves potential fire hazards.
