What is a Fuel Pump Relay?
The fuel pump relay is an electromechanical switch that controls the power supply to the fuel pump. When the ignition is turned on, the relay receives a signal from the engine control module (ECM) to activate the fuel pump. This process ensures that fuel is delivered to the engine at the right pressure for optimal performance.
How Does the Ford Ranger Fuel Pump Relay Work?
The operation of the fuel pump relay involves several steps:
- When the ignition is turned on, the ECM sends a signal to the relay.
- The relay closes its contacts, allowing electricity to flow to the fuel pump.
- The fuel pump is activated, drawing fuel from the tank and sending it to the engine.
- Once the engine is running, the relay continues to supply power to the pump until the engine is turned off.
What Happens When the Fuel Pump Relay Fails?
A faulty fuel pump relay can lead to various issues, including:
- The engine may not start due to insufficient fuel pressure.
- Intermittent stalling while driving.
- Increased difficulty in starting the engine.
- Unusual noises from the fuel pump or electrical system.
