Introduction
If you are dealing with a fuel pump problem in your vehicle, there’s a good chance that the fuel pump relay is the culprit. The fuel pump relay is responsible for supplying power to the fuel pump, and if it fails, the fuel pump will not function. In this guide, we will provide you with a comprehensive overview of the fuel pump relay wiring diagram, including its function, location, and how to troubleshoot it.
What is a Fuel Pump Relay?
The fuel pump relay is an essential component of the fuel system, responsible for regulating the power supply to the fuel pump. The relay is typically located in the engine compartment, near the battery or fuse box. When the ignition is turned on, the relay sends a signal to the fuel pump to start pumping fuel to the engine. When the ignition is turned off, the relay stops the power supply to the fuel pump.
Fuel Pump Relay Wiring Diagram
The fuel pump relay wiring diagram consists of several components, including the relay itself, the battery, the ignition switch, the fuel pump, and the fuse. The relay is typically a small black box with several wires attached to it. The wiring diagram will show you which wire is responsible for what function.
Fuel Pump Relay Location
The fuel pump relay is typically located in the engine compartment, near the battery or fuse box. It may be located on the firewall or on the inner fender. The location can vary depending on the make and model of your vehicle. Consult your owner’s manual or a service manual to locate the fuel pump relay.
