When it comes to keeping your vehicle running smoothly, the fuel pump is one of the most important components that you need to pay attention to. Without a properly functioning fuel pump, your engine won’t be able to get the fuel it needs to operate. However, understanding your vehicle’s fuel pump wiring can be challenging. In this article, we’ll take a deep dive into the world of fuel pump wiring and explore the 91 S10 fuel pump wiring diagram in detail.
What is a fuel pump?
Before we dive into the details of the 91 S10 fuel pump wiring diagram, let’s take a moment to understand what a fuel pump is and how it works. Simply put, a fuel pump is responsible for pumping fuel from the fuel tank to the engine. Most modern vehicles use an electric fuel pump, which is controlled by the vehicle’s computer.
When you turn the ignition key, the vehicle’s computer sends a signal to the fuel pump relay, which activates the fuel pump. The fuel pump then pressurizes the fuel system and sends fuel to the engine. Once the engine is running, the vehicle’s computer continues to monitor the fuel system and adjusts the fuel delivery as needed to ensure optimal performance.
