If you're experiencing fuel pump problems (e.g., the engine won't crank, or the fuel pump isn't priming), the issue likely lies with:
* The fuel pump itself: It might be faulty and need replacement.
* The fuel pump relay: This relay controls the power to the pump; it might be faulty or stuck.
* Wiring: A problem with the wiring to the fuel pump can prevent it from working.
* Fuel pump fuse: A blown fuse will prevent power from reaching the pump.
* Inertia switch: Some vehicles have an inertia switch (a safety device that cuts power to the fuel pump in a collision) that may have tripped. This is often located under the dash or in the engine compartment. Check your owner's manual for its location if you suspect this is the problem.
Before replacing the fuel pump (which is an expensive repair), you should check the relay and fuse first. These are relatively easy to check and replace. Consult your owner's manual for their locations and how to test them. You might also want to have a mechanic diagnose the problem to pinpoint the exact cause.
