To find the solution, you need to consult your owner's manual. It will show you the location of the underhood fuse box and the interior fuse panel (if applicable). While the manual might not directly point to a "fuel pump fuse," it should detail the relay related to the fuel pump, which you'll likely need to check or replace. Sometimes a blown in-line fuse in the harness itself is the culprit.
Troubleshooting Steps (use caution when working with vehicle electrical systems):
1. Consult your owner's manual: This is the most important step. Locate the fuse box diagrams. Look for relays related to the fuel injection system, fuel pump, or engine control module (ECM).
2. Check the fuel pump relay: This is more likely the point of failure than a blown fuse. The manual will tell you its location and how to test it. You can often swap it with a similar relay to see if that resolves the problem (make sure to label where it came from!).
3. Visual Inspection of Wiring: Carefully inspect the wiring harness for any signs of damage, melting, or corrosion, paying attention to the area near the fuel pump itself.
4. Professional Assistance: If you are uncomfortable working with car electrical systems, it's best to take your Mountaineer to a qualified mechanic. Incorrectly diagnosing and replacing parts can lead to further problems.
In short: There's no single "fuel pump fuse" to easily find. You need to consult your owner's manual and likely focus on the fuel pump relay.
