What does a fuel pump relay do?
The fuel pump relay is the electronic switch that controls power to the fuel pump. It is found on virtually all vehicles with an internal combustion engine and is often located in the fuse box which can be found in the engine bay. The fuel pump relay is also responsible for helping your vehicle to start. The relay activates the fuel pump to pressurise the fuel system as you turn the key.
The fuel pump is a small pump which sends the fuel from the tank to the engine. The pump may be mechanically worked by the engine, but on most modern cars it’s electrically-powered. In this case it’s usually found next to or even inside the fuel tank.
This process of pumping fuel from the tank to the engine is essential in the smooth running of your vehicle, therefore a faulty fuel pump relay will cause major performance and drivability issues with your vehicle.
How often should a fuel pump relay need replacing?
There is no set lifespan of a fuel pump relay, however the relay is designed to last the life of the car, but due to its constant use and the high temperatures it is exposed to, it will not usually last that long. Over time, the fuel pump relay may begin to show signs of wear and will have to be replaced.
The most commonly damaged portions of the fuel pump relay that tend to malfunction first are the coil and contact points. Usually, these parts of the relay will begin to oxidise and rust over time.
