3. Operating Instructions
The Shanrya Fuel Pump Relay operates automatically as an integral part of your vehicle's engine management system. Its primary function is to control the electrical power supply to the fuel pump.
3.1 Automatic Operation
- When the ignition is turned on, the engine control unit (ECU) sends a signal to the fuel pump relay.
- The relay then closes, allowing electrical current to flow to the fuel pump, which primes the fuel system.
- During engine operation, the relay remains closed, continuously supplying power to the fuel pump.
- If the engine stalls or the ignition is turned off, the relay opens, cutting power to the fuel pump for safety.
No manual intervention is required for the operation of this relay once correctly installed.
4. Maintenance
The Shanrya Fuel Pump Relay is designed for durability and typically requires no routine maintenance. However, periodic visual inspection can help ensure its longevity and proper function.
4.1 Inspection Guidelines
- During routine vehicle service, inspect the relay and its connections for any signs of corrosion, loose wiring, or physical damage.
- Ensure the relay is securely seated in its socket.
- If any damage or excessive corrosion is observed, consider replacing the relay to prevent potential fuel system issues.

5. Troubleshooting
If you experience issues with your vehicle's fuel system, the fuel pump relay could be a potential cause. Here are some common symptoms and troubleshooting steps.
5.1 Common Symptoms of a Faulty Fuel Pump Relay
- Engine Cranks but Does Not Start: The fuel pump may not be receiving power to prime the system.
- Engine Stalls While Driving: Intermittent power loss to the fuel pump can cause the engine to cut out.
- No Fuel Pump Hum: When the ignition is turned to the 'ON' position (before starting), you should hear a brief hum from the fuel pump. Absence of this sound may indicate a relay issue.
- Check Engine Light: Some vehicles may trigger a diagnostic trouble code related to fuel system issues.
5.2 Troubleshooting Steps
- Check Fuses: Before suspecting the relay, inspect the fuel pump fuse in your vehicle's fuse box. A blown fuse will prevent the relay from receiving power.
- Inspect Connections: Ensure the relay is fully seated and its electrical connections are clean and free of corrosion.
- Swap with a Known Good Relay: If possible, swap the fuel pump relay with another identical, non-critical relay from your vehicle (e.g., horn relay) to see if the problem resolves or shifts.
- Professional Diagnosis: If the issue persists after basic checks, it is recommended to consult a qualified automotive technician for a thorough diagnosis.
