If you're experiencing fuel-related problems, the issue likely lies elsewhere:
* Fuel pump relay: This relay, located in the underhood fuse box, might be faulty and need replacement.
* Inert switch: Some Explorers have an inertia switch, designed to cut power to the fuel pump in a collision. This switch is usually located under the dashboard, sometimes near the driver's side. Check if it's tripped (usually a red button that needs to be pushed back in).
* Fuel pump itself: The pump might be failing due to age or wear.
* Wiring or connectors: A problem with the wiring to the fuel pump or its connectors can interrupt power.
* PCM issues: In rare cases, a problem with the PCM can prevent it from sending power to the fuel pump. This requires diagnostic tools to determine.
* Low fuel level: Make sure you actually have fuel in the tank!
Troubleshooting Steps:
1. Check the fuel level: This is the simplest and most common reason for a no-start.
2. Check the inertia switch: Locate it and see if it needs to be reset.
3. Check the fuel pump relay: Locate it in the fuse box (consult your owner's manual), remove it, and visually inspect for damage. You can also try swapping it with a similar relay (if you have a spare) to see if that solves the problem.
4. Listen for the fuel pump: Turn the key to the "on" position (don't crank the engine). You should hear a brief humming sound from the fuel pump in the fuel tank. If you don't hear it, the pump or its circuit might be faulty.
If none of these steps resolve the issue, you'll need to consult a mechanic or use a diagnostic scanner to pinpoint the problem. A code reader will be able to provide more specific information about potential malfunctions in your vehicle's systems.
