After examining the fuel pumps returned under claim for the above vehicles, it has been found that a high percentage of returns have no operating fault found with them. The normal complaint is “not pumping”, or “fuel starvation”. In some cases the fault may be cured when a new fuel pump is fitted, but returns shortly afterwards. There are two common causes of these symptoms on the vehicle, besides the fuel pump: 1) The Rubber Fuel Supply Pipe This may be perished or weakened, resulting in a partial or total collapse of the internal bore, restricting the fuel flow. The perishing of the pipe can also lead to air leaks on the suction feed to the fuel pump, so that the pump sucks air as well as fuel, reducing the lift efficiency of the fuel pump. 2) The In-Line Fuel Filter The filter should be changed at intervals of 20,000miles (32,000Km). Failure to do so will result in a build up of sediment particles blocking the filter, reducing the fuel flow. This is especially so on older vehicles where corrosion takes place within the fuel tank and metal feed pipes. In order to ensure that the fuel feed system operates at its full potential, it is recommended that both of the above items are checked, and/or replaced, before fitting a new fuel pump.

The in-line fuel filters fitted to fuel delivery modules in Freelander 2.5-liter KV6 gasoline vehicles may be manufactured away from specification. The fuel filters may contain an uncontrolled amount of the adhesive used to bond the filter paper to the filter casing; the adhesive may not have been adequately cured; or the fuel pump inlet stub pipe hole on the fuel filter may have inadequate dimensional controls. In any of these cases, it is possible for these conditions to prevent adequate fuel flow through either restrictions in the filter or cracking of the pump stub pipe. This leads to increased pump motor use to maintain the required engine-demanded fuel and premature wear of the fuel pump motor brushes. In the event of restricted fuel flow, the vehicle may suffer one or more of the following symptoms: rough running and malfunction indicator lamp (MIL) illumination; poor / no start; engine stumble or hesitation; or engine cut-out / stall with the possibility of Diagnostic Trouble Codes (DTC) P0301, P0302, P0303, P0304, P0305, P0306, P0171, P0174, or P0316 stored. Action: Refer to the Repair Procedure outlined below to replace the fuel pump module. CAUTION: A Midtronics PSC-550 Vehicle Power Supply must be connected to the vehicle battery during IDS diagnosis / module programming. 4. Connect the Midtronics PSC-550 Vehicle Power Supply to the vehicle battery. CAUTION: IDS with T4 software DRG TL 36 5. Connect T4 to the vehicle and begin a new diagnostic session. 6. Select ‘System Diagnostics’. 7. Enter ‘Make and MY’ and correct VIN for the current vehicle. NOTE: Any DTCs not listed in step 3 are to be investigated / repaired as a separate repair. 8. Select ‘Fault Code Diagnostics’. 9. Read and clear stored fault codes. 10. Exit the current session when the task is completed. 11. Disconnect T4 and the Midtronics PSC-550 Vehicle Battery Supply from the vehicle.

Some 2006 Frontier, Xterra, and Pathfinder vehicles are not covered by this bulletin; they are covered under Nissan Recall Campaign NTB10-031 (that addresses the separate issue of the fuel gauge reading 1/4 full when the tank is empty). Check Service COMM to see if the vehicle you are working on is instead covered under that Campaign. IF YOU CONFIRM: The fuel gauge is erratic, inaccurate, or inoperative. And/Or The MIL is “ON” with DTC P0461, P0462, or P0463 stored in Self-Diagnosis. ACTIONS: Replace the fuel level sending unit with the one from the Parts Information section of this bulletin. • Refer to section FUEL LEVEL SENSOR UNIT, FUEL FILTER AND FUEL PUMP ASSEMBLY Disassembly and Assembly in the FL section of the appropriate Electronic Service Manual for details on the procedure, if needed. NOTE: Do not replace the entire fuel pump assembly for this incident, if it should occur.
