If you're having fuel pump problems, the issue is likely one of the following:
* Blown Fuel Pump Fuse/Relay: Check your owner's manual or fuse box diagram to locate and check the fuses and relays related to the fuel pump. A blown fuse or relay will prevent the pump from operating. Replace it with the correct amperage fuse or relay.
* Faulty Fuel Pump: The fuel pump itself may have failed. This requires replacing the pump, a more involved repair.
* Fuel Pump Relay Wiring: There could be a problem with the wiring to the fuel pump relay. This requires tracing the wires and possibly repairing or replacing damaged wiring.
* Inertia Switch: Some cars have an inertia switch that cuts power to the fuel pump in a collision to prevent fuel leaks. This switch is usually located under the dash or in the engine compartment. Check if it's tripped and reset it if necessary. The location will be shown in your owner's manual.
* Low Fuel Level: Though not technically a "fuel pump" problem, running the car extremely low on fuel can sometimes cause issues.
Before doing any repairs, disconnect the negative battery cable to prevent electrical shocks or short circuits. If you're not comfortable working on your car's electrical system, it's best to take it to a qualified mechanic.
