When it comes to the fuel system of any vehicle, the fuel pump is one of the most important components. It’s responsible for delivering fuel from the gas tank to the engine, and if it fails, your vehicle won’t be able to run. If you own a 2000 Ford Focus, it’s important to know the wiring diagram for the fuel pump, as this can help you troubleshoot any issues you may be having with your vehicle’s fuel system.
What is a Fuel Pump Wiring Diagram?
A fuel pump wiring diagram is a diagram that shows the electrical connections for the fuel pump. It’s essentially a road map that shows you how to connect the various wires to the fuel pump, and it’s essential for troubleshooting fuel system problems. The wiring diagram for a 2000 Ford Focus fuel pump will show you how to connect the wires for the pump relay, the fuel pump inertia switch, and the fuel pump itself.
How to Read a Fuel Pump Wiring Diagram
Before we get into the specifics of the 2000 Ford Focus fuel pump wiring diagram, it’s important to understand how to read a wiring diagram in general. Wiring diagrams can be confusing at first, but once you know the basics, they become much easier to understand.
The first thing to understand is that a wiring diagram is essentially a map of the electrical connections in a vehicle. Each wire is represented by a line on the diagram, and each component is represented by a symbol. The symbols can vary depending on the specific vehicle and the diagram, so it’s important to refer to the legend or key to understand what each symbol represents.
The other important thing to understand is that wiring diagrams are typically drawn as if you’re looking at the vehicle from the front, with the hood open. This means that the front of the vehicle is on the left side of the diagram, and the rear of the vehicle is on the right side of the diagram.

Now that you know the basics of how to read a wiring diagram, let’s take a look at the 2000 Ford Focus fuel pump wiring diagram. This diagram shows the electrical connections for the fuel pump, fuel pump relay, and fuel pump inertia switch.
| Wire Color | Component | Connection |
|---|---|---|
| Yellow/Black | Fuel Pump Relay | Pin 2 |
| Gray/Black | Fuel Pump Relay | Pin 5 |
| Dark Green/Yellow | Fuel Pump Inertia Switch | Pin 1 |
| Black/Pink | Fuel Pump Inertia Switch | Pin 2 |
| Orange/Light Blue | Fuel Pump | Pin 1 |
| Black/Pink | Fuel Pump | Pin 2 |
Fuel Pump Relay
The fuel pump relay is responsible for turning on the fuel pump when the key is turned to the “on” position. It’s located in the power distribution box in the engine compartment, and it’s connected to the fuel pump by two wires: yellow/black and gray/black. The yellow/black wire is connected to pin 2 on the fuel pump relay, and the gray/black wire is connected to pin 5.
Fuel Pump Inertia Switch
The fuel pump inertia switch is a safety feature that shuts off the fuel pump in the event of a collision. It’s located in the trunk of the vehicle, and it’s connected to the fuel pump by two wires: dark green/yellow and black/pink. The dark green/yellow wire is connected to pin 1 on the fuel pump inertia switch, and the black/pink wire is connected to pin 2.
Fuel Pump
The fuel pump itself is responsible for pumping fuel from the gas tank to the engine. It’s located inside the gas tank, and it’s connected to the fuel pump relay and fuel pump inertia switch by two wires: orange/light blue and black/pink. The orange/light blue wire is connected to pin 1 on the fuel pump, and the black/pink wire is connected to pin 2.
