2011-2012 Honda CR-Z Fuel Pump: Diagnosis, Replacement, and Used Buying Tips

Symptoms of a Failing Fuel Pump

A failing fuel pump in a Honda CR-Z can cause a range of issues, from subtle performance problems to a car that won't start. Here are the most common signs to watch for:

• Engine Hesitation or Sputtering: The car may hesitate or sputter during acceleration, especially under heavy load. This happens when the pump can't supply enough fuel to meet the engine's demand.
• Loss of Power: You might notice the car feels sluggish or lacks its usual power. A weak pump can't maintain the required pressure in the fuel system.
• Engine Stalling: The engine may stall unexpectedly, sometimes shortly after starting or while driving. This can be intermittent at first but typically gets worse.
• Car Will Not Start: The most definitive symptom is a no-start condition. The engine will crank over but won't fire up because it's not receiving any fuel. You can often test this by turning the key to the 'ON' position (without starting) and listening for a faint humming or whining sound from the rear of the car for about two seconds. If you hear nothing, the pump is likely not working.
• Whining Noise from Fuel Tank: A loud, high-pitched whining sound from the fuel tank area can indicate the pump motor is straining and about to fail.
• Check Engine Light: A failing fuel pump can trigger a Check Engine Light. Common codes include P0087 (Fuel Rail/System Pressure - Too Low), which points directly to a fuel delivery issue.
• Inaccurate or Flashing Fuel Gauge: Since the fuel level sending unit is part of the assembly, a faulty module can cause the fuel gauge to read empty, full, or fluctuate wildly.

Known Issues, Recalls, and TSBs

As of mid-2026, there are no active safety recalls from the National Highway Traffic Safety Administration (NHTSA) for the fuel pump on the 2011-2012 Honda CR-Z. While Honda has issued large-scale recalls for fuel pumps on many other models from later years (2018-2020), the 2011-2012 CR-Z is not included in those campaigns.

There are also no widespread Technical Service Bulletins (TSBs) pointing to a common defect with the fuel pump module itself for this vehicle. One related TSB, #10129552, addresses the Check Engine Light with EVAP system leak codes (P0455/P0456), but this is not a fuel pump failure.

Buying a Used Fuel Pump Assembly

For many owners, a low-mileage used OEM fuel pump is a smart, cost-effective alternative to an expensive new unit. The key is to buy a quality part. Here’s what to look for:

• Verify the Part Number: The correct OEM part number for the 2011-2012 Honda CR-Z fuel pump module is 17045-SZT-L00. Always match this number. While pumps from other Hondas might look similar, differences in pressure, size, or electrical connectors can cause problems.
• Physical Inspection: When you receive the part, inspect it carefully. Look for cracks in the white plastic housing, especially around the fuel line connections. Check the electrical connector pins for any signs of corrosion, melting, or damage. Ensure the wiring is intact.
• Ask for Mileage and VIN: Reputable sellers of used parts should be able to provide the mileage and VIN of the vehicle the part came from. A pump from a car with under 100,000 miles is a much safer bet than one with unknown or very high mileage.
• Check the Fuel Strainer: Look at the small filter sock at the bottom of the pump. If it is black and full of sediment, it suggests the donor car may have had a contaminated fuel tank, and the pump may have been strained. A clean, light-colored strainer is a good sign.
• Why Used OEM is Often Better Than New Aftermarket: While cheap new aftermarket pumps are available, they are a gamble. They are notorious for premature motor failure or, more commonly, having inaccurate fuel level sending units that cause your gas gauge to be unreliable. A genuine used Honda pump (like 17045-SZT-L00) was built to Honda's specifications for fit, pressure, and sensor accuracy.

Replacement Overview & Difficulty

Replacing the fuel pump on a 2011-2012 CR-Z is a moderately difficult job that involves working with flammable gasoline and pressurized fuel lines.

• Difficulty Rating: 4 out of 5
• DIY Feasible: Yes, for experienced mechanics. Not recommended for beginners.
• Estimated Time: 1.5 - 2.5 hours

The basic steps involve:

1. Relieve Fuel Pressure: Start the engine and pull the fuel pump fuse or relay until the engine stalls.
2. Disconnect the Battery: Disconnect the negative battery terminal.
3. Access the Pump: The pump is located in the fuel tank, under an access panel. This panel is typically found under the center console or rear cargo area trim.
4. Remove Connections: Carefully clean the area to prevent debris from falling into the tank. Disconnect the electrical connector and the fuel line.
5. Remove the Locking Ring: A special tool is recommended, but the ring can sometimes be carefully tapped loose with a brass punch and hammer.
6. Swap the Assembly: Lift the old pump assembly out carefully, trying not to bend the fuel level float arm. Install the new assembly with a new tank seal/gasket.
7. Reassemble: Install the locking ring, reconnect the fuel line and electrical connector, and reinstall the access panel and interior trim. Reconnect the battery, add fuel if the tank is empty, and cycle the key a few times to prime the system before starting.
