Acura RL Fuel Pump and Fuel Injection

1. Fuel Pump: In your RL, the fuel pump delivers fuel from the tank to the engine. It ensures a consistent supply for smooth operation.
2. Fuel Injection Relay: This relay controls the power supply to the fuel pump.

Symptoms of Failure:

• Stalling: Your RL might stall due to lack of fuel supply.
• Difficulty Starting: A faulty relay or pump can make starting the car tough.
• Engine Performance Issues: Hesitation or surging during acceleration.

Troubleshooting:

1. Check the Fuel Pump: Listen for a humming noise from the fuel tank when you turn the ignition. No sound could indicate a problem.
2. Inspect the Fuel Injection Relay: Locate the relay in the fuse box. A damaged relay may prevent the pump from receiving power.

Locating and Replacing the Fuel Pump:

1. Locate the Pump: In the RL, the fuel pump is inside the fuel tank.
2. Access the Tank: You’ll need to remove the back seat to reach the tank’s access panel.
3. Replace the Pump: After draining the tank, you can remove and replace the pump. Be cautious of fuel spillage.

Locating and Replacing the Fuel Injection Relay:

1. Find the Relay: It’s in the fuse box, under the hood.
2. Identify the Relay: Refer to your RL’s manual to identify the correct relay.
3. Replace the Relay: Simply unplug the old relay and plug in a new one.

OBD Codes:

The engine light may be on.  Along with the engine light, you may see these.

• P0230 to P0233: These codes indicate issues with the fuel pump primary circuit.
• P0627 to P0629: Related to the fuel pump control circuit.

Final Thoughts

Starting and stalling issues in your 1996-2006 Acura RL can often be traced back to the fuel pump or fuel injection relay. By following this guide, you can identify and resolve these. Remember, if you’re unsure or uncomfortable performing these tasks, it’s always best to consult a professional mechanic.
