Jan 9, 2024 · The fuel pump relay is the electronic component found on all vehicles with an internal combustion engine. To “relay” means “to receive and pass on”. Whenever the ignition is turned on, the fuel pump relay will supply or “pass on” a consistent voltage to the fuel pump.
A fuel pump relay operates as an intermediary between the engine control module (ECM) and the fuel pump. When the engine is turned on, the ECM sends a signal to the fuel pump relay to activate the fuel pump.
Dec 2, 2021 · The most common sign of a bad fuel pump relay is an engine that cranks but doesn’t start. A fuel pump relay will typically fail in the open position, preventing voltage from reaching the fuel pump. As a result, the engine will be starved of fuel and refuse to run.
Feb 23, 2024 · Check your fuel pump relay regularly: Inspect the fuel pump relay for signs of damage or wear, such as corrosion or melted plastic. If you notice any issues, replace the fuel pump relay immediately.
Jan 8, 2016 · The fuel pump relay is an electronic component that is found on virtually all vehicles equipped with an internal combustion engine. It is often found in the fuse box located in the engine bay and functions as the primary electronic switch that controls power to the fuel pump.
May 1, 2024 · If you notice a problem with your fuel pump, such as no noise coming from it or your engine not starting, there could be a problem with the fuel pump relay, which controls the electric current running through the pump.

As you turn the key on the ignition, the fuel pump relay activates the fuel pump to develop pressure in the fuel system. If this relay starts to fail, you will notice that the engine’s performance will deteriorate over time. It will be incapable of energizing the fuel pump.
Aug 8, 2023 · The fuel pump relay is responsible for controlling the fuel pump‘s operation, ensuring that fuel is delivered to the engine at the right pressure. If the relay is faulty, it can lead to a no-start condition or intermittent fuel supply problems.
Oct 19, 2016 · The fuel pump has a relay that fails when there is no audible humming sound as the ignition is turned and when the car cranks after longer than usual.
