Common signs include difficulty starting the engine, a noticeable drop in engine power during acceleration, stalling while driving, or poor fuel efficiency. If you experience any of these symptoms, it may be time to investigate further.

Check Fuel Pressure

One of the most effective ways to diagnose high-pressure fuel pump issues is by measuring the fuel pressure. You will need a fuel pressure gauge for this task. Locate the fuel rail on the engine and connect the gauge to the service port. Check the pressure reading when the ignition is turned on (but the engine is not running). For most Honda CR-V models, the ideal fuel pressure is typically between 40 to 50 psi. If the reading is significantly lower, the fuel pump may be failing.

Inspect Electrical Connections

Next, examine the electrical connections leading to the fuel pump. A faulty connection can cause the pump to underperform. Check for any signs of corrosion, loose wires, or damaged connectors. Additionally, a multimeter will be used to test the voltage at the fuel pump connector while the engine is running. The voltage should be within the manufacturer’s specifications. If it’s low, there may be an issue with the wiring or the fuel pump relay.

Listen for Pump Operation

Finally, when you turn the ignition key to the “ON” position, listen for a humming sound from the fuel tank. This noise indicates that the pump is operating. If you don’t hear anything, it could signal a failure in the pump itself or an issue with the electrical system. Following these steps, you can effectively diagnose high-pressure fuel pump issues in your Honda CR-V and determine whether repairs or replacements are necessary.
