Fuel relay location on a 2003 ford expedition 5.4l?

The fuel pump relay location on a 2003 Ford Expedition with a 5.4L engine is in the Power Distribution Box (PDB), also sometimes called the fuse box under the hood. It's not always clearly labeled as "Fuel Pump Relay". You'll likely find it within the larger fuse box, and it might be labeled as something like:

* Fuel Pump

* EFI Relay

* Engine Control Relay (Possibly; it depends on if it's a combined relay for both)

To find it:

1. Open the hood: Locate the latch inside the vehicle and release it.

2. Locate the Power Distribution Box (PDB): This is usually a large plastic box located in the engine compartment, often near the battery. It should have a cover with numerous fuses and relays.

3. Consult your owner's manual: Your owner's manual will have a diagram of the PDB showing the location of all fuses and relays. This is the best way to locate the correct relay.

4. Look for markings: Carefully examine the relays within the box. Look for any markings that suggest it's related to the fuel system. You may need a flashlight to see clearly.

Important Note: If you're unsure, do not attempt to replace any relay without positively identifying it first. Replacing the wrong relay could cause further damage to your vehicle. If you are not comfortable working on your vehicle's electrical system, it is best to consult a qualified mechanic.
