Known issuesFuel module reservoir assembly: fuel pump wire connectors may overheat - recall 05V-1552

  1. Recall2000 GMC YUKON XL ・ —

    Fuel Module Reservoir Assembly Overheating Recall

    1. 1Fault

      • Some vehicles were built with fuel module reservoir assemblies whose fuel pump wires and/or connectors may overheat under certain operating conditions.
      • If the exposed ignition circuit wire shorts to ground, the fuel pump fuse blows, disabling the fuel pump and causing an engine stall or no-start; if the ignition circuit or ground wire shorts to the fuel level sender card wires, fuel level readings may be inaccurate.
      • If enough heat reaches the pass-through connector, a hole may form in it, which may turn on the Service Engine Soon light during the emission system diagnostics routine; fuel vapor, and in some cases liquid fuel, may leak from the tank through the hole.
      • If enough fuel leaked out and an ignition source were present, a vehicle fire could occur.

    2. 2Finding the cause

      Possible causes

      • Fretting corrosion caused by vibration inside the tank was identified as the cause of high resistance within the fuel pump connector.

    3. 3Correction

      Repair

      1. Dealers remove the fuel tank, remove the fuel module reservoir assembly and install a new service kit, which includes a new pass-through connector and a wiring harness for the fuel pump and fuel sender card.
      2. Start by disconnecting the negative battery cable, then remove and discard the "ECM B" fuse.
      3. In the revised bulletin, the fuel and EVAP pipes are capped with J 41413-300, EVAP Cap/Plug Kit, to prevent fuel system contamination.
      4. Remove the 4 pin Metri Pack 150 electrical connector from the vehicle's body harness.
      5. Connect the new GT280 connector to the vehicle's body harness with the 4 butt splice connectors contained in the kit.

    Cause
    CERTAIN TRUCKS AND SPORT UTILITY VEHICLES WERE BUILT WITH FUEL MODULE RESERVOIR ASSEMBLIES THAT CONTAIN FUEL PUMP WIRES CONNECTORS MAY OVERHEAT UNDER CERTAIN OPERATING CONDITIONS.
    Remedy
    DEALERS WILL REMOVE THE FUEL TANK, AND REMOVE THE MODULE RESERVOIR ASSEMBLIES FROM THE TANK, AND INSTALL A NEW SERVICE KIT FREE OF CHARGE. AN INTERIM LETTER TO OWNERS WAS MAILED ON MAY 25, 2005. THE OWNERS WERE RE-NOTIFIED ON OCTOBER 19, 2005, SINCE PARTS ARE NOW AVAILABE. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438 AND GMC AT 1-866-996-9463.
    Consequence
    IF THE IGNITION CIRCUIT WIRE IS EXPOSED, THE FUEL PUMP FUSE WILL BLOW, DISABLING THE FUEL PUMP AND CAUSING AN ENGINE STALL OR NO-START CONDITION. IF SUFFICIENT HEAT IS CONDUCTED TO THE PASS-THROUGH CONNECTOR, A HOLE IN THE CONNECTOR MAY RESULT, WHICH MAY CAUSE A 'SERVICE ENGINE SOON' LIGHT TO BE ILLUMINATED DURING THE EMISSION SYSTEM DIAGNOSTIC ROUTINE. FUEL VAPOR AND IN SOME CASES LIQUID FUEL MAY LEAK OUT OF THE FUEL TANK THROUGH THE HOLE IN THE CONNECTOR BODY. FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN A FIRE. ALSO IF THE IGNITION CIRCUIT OR GROUND WIRE IS EXPOSED AND SHORTS TO THE FUEL LEVEL SENDER CARD WIRES, INACCURATE FUEL LEVEL READINGS MAY RESULT.

Known issuesFuel gauge reads low or drops to empty in Park / Neutral (normal characteristic)1

  1. Manufacturer communication2000–2006 GMC YUKON XL ・ 2017-08-15

    Fuel Gauge Accuracy—Preliminary Information

    1. 1Fault

      • The fuel gauge may be inaccurate or drop to empty (E) with the low fuel light coming on.
      • The condition is most apparent when the gauge is at or below the quarter (1/4) tank mark.

    2. 2Finding the cause

      Possible causes

      • On an automatic transmission no buffering of the fuel gauge takes place when the transmission is in park or neutral.

      Steps to confirm (in the document’s order)

      1. Try to duplicate it by driving a short distance in reverse and stopping (to make fuel slosh), shifting to park or neutral and then to drive.
      2. Note how the vehicle is being parked (on an incline, front of the vehicle up hill or down hill).

    3. 3Correction

      Caution

      • This is a normal characteristic and no repairs are necessary.

    Open the manufacturer’s document (PDF) ↗ The points above were read from this document.

    Remedy
    This Preliminary Information communication provides information to the technician about vehicles that have an inaccurate fuel gauge. Technician should drive the vehicle to duplicate the concern. The fuel gauge will have a tendency to falsely indicate a lower fuel level than what is actually present. The fuel gauge will take a few minutes to show the correct fuel level. On vehicles equipped with an automatic transmission no buffering takes place when the transmission is in park or neutral. This is a normal characteristic and no repairs are necessary. On vehicles equipped with a manual transmission the fuel gauge is buffered in all gears and neutral. There is a timer which starts to count up when the clutch is depressed. When this timer reaches its calibrated value the buffering stops. This is a normal characteristic and no repairs are necessary.

    3. 3Correction

    Read the sentences of the record
    Remedy
    This Preliminary Information communication provides information to the technician about vehicles that may have a buzz noise at idle after fuel pressure regulator replacement. Technician will need to gain access to the fuel pump. After gaining access to the fuel pump check the power and ground for voltage drop with the key in the off from the fuel pump to the battery post. Technician should also check the pin fit and terminal drag. Technician may replace the fuel pump connector with the updated part using the latest version service bulletin 04-06-04-088C. Technician should inspect voltage drop points at the UBEC, fuel pump relay, ground at the frame and the battery cable grounds. If excessive resistance is found at the crimps, replace the crimp n seal splice sleeves for the affected circuits. If the circuits do not have high resistance replace the regulator using part number 19236428.

    Engine Check Lamp P0442 Evaporative Emissions System Notification

    1. 1Fault

      • The service engine soon lamp (MIL) is on for DTC P0442, but a leak cannot be verified with the system test in the service information.

    2. 2Finding the cause

      Steps to confirm (in the document’s order)

      1. With the scan tool, command the EVAP system CLOSED, start the engine and watch the tank pressure sensor value for about two minutes.
      2. If the tank pressure value changes (shows vacuum), remove the purge solenoid and pressurize its fuel tank side with the GE 41413-A / J 41413-A tester.
      3. If the tank pressure value does not change, install the CH-48096 adaptor between the purge line from the canister and the purge solenoid; use no other adaptor or pressurization method.
      4. With the EVAP system CLOSED, pressurize through the adaptor and let the system stabilize, watching the gauge for at least 5 minutes, then add smoke.
      5. Look for smoke or UV trace fluid at the purge solenoid, the engine side, the fuel cap or capless fill door, and the canister vent solenoid filter or fresh-air line.
      1 more points

    3. 3Correction

      Repair

      • If smoke passes through the purge solenoid, replace the purge solenoid.

      Caution

      • After verifying P0442, do not disturb any fuel system component before testing.
      • Test pressure must not exceed 13 in H2O (0.5 PSI (= 3.45 kPa)); more can make components perform inaccurately and lead to misdiagnosis.
      • A large temperature difference between vehicle, shop and tester seriously affects accuracy; let the vehicle adjust to shop temperature first.

    Remedy
    This Preliminary Information communication provides information to the technician about vehicles that have a Service Engine Soon Malfunction Indicator Lamp. Technician may find Diagnostic Trouble Code P0442. Technician will need to review Techlink article from May 2013 titled "Using the Evaporative Emissions System Tester" Technician will need to follow these steps to help diagnose the issue. First after the P0442 has been verified do not disturb any of the fuel system components. The technician now can use the scan tool to close the Evaporative Emissions System. If possible change the tank pressure sensor units from inch_H2O to milimeter_Hg for better resolution. Now the vehicle can be stared to monitor the tank pressure sensor output value for approximately two minutes. If the tank pressure sensor value does change, pressurize the fuel tank side of the purge solenoid with the GE 41413-A / J 41413-A and the necessary adaptors. Now add smoke and allow pressure to stabilize for 2 minutes. If smoke is allowed to pass through the purge solenoid, replace the purge solenoid. If the tank pressure sensor value does not change, then install CH-48096 adaptor between the purge line from the canister and the purge solenoid. With the Evaporative Emissions System closed, pressurize the system through the CH-48096 adaptor and allow the system to completely stabilize, by observing the Press / Vac Gauge for a minimum of 5 minutes. Now add smoke to the system with GE 41413-A / J 41413-A after system stabilization. Now inspect the purge solenoid, engine side, fuel cap, canister vent solenoid filter and any line quick connects. When the leak is unable to be located, test under a vacuum condition. his type of leak may be detected by using the scan tool Purge/Seal function to create a vacuum in the Evaporative Emissions System and then observe the FTP sensor parameter for vacuum decay.
