Service Information
Purpose:
This bulletin provides a service procedure to determine if a fuel tank sending unit requires replacement on certain 2007 Isuzu Ascender vehicles. The fuel tank sending unit on this vehicle may have a fractured internal port. A fractured port will not deliver fuel to the engine at the designed pressure. If this were to occur, it could result in an extended start, sluggish acceleration, and/or the illumination of the check engine light.
NOTE:
This service procedure should be completed as soon as possible on involved vehicles currently in dealer inventory and customer vehicles that return to the dealer/retailer for any type of service during the New Vehicle Limited Warranty coverage period.
Service Procedure
Tools Required Required
^ Kent Moore J 45722 Fuel Tank Sending Unit Wrench or equivalent.
1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in the Service Manual.
2. Locate the fuel tank label (1), which is on the backside of the fuel tank (2) below the fuel tank filler neck.
3. Inspect the fuel tank for a white "X" on the fuel tank and/or a green "C" on the barcode.
^ If a white "X" on the fuel tank and/or a green "C" on the barcode is found, the fuel sender assembly does not require replacement. No further action is required.
^ If a white "X" on the fuel tank and/or a green "C" on the barcode is not found, proceed to Step 4 for additional inspection.
4. Compare the fuel tank serial number printed on the fuel tank label (1) to the fuel tank serial number (sequencing) range listed:
^ If the serial number of the tank is not within the ranges above, lower the vehicle. No further action is required.
^ If the serial number of the tank is within the ranges above, remove and replace the fuel sender assembly. Proceed to Step 5 in this bulletin.
5. Remove the fuel tank from the vehicle. Remove the fuel sender assembly from the fuel tank. Refer to Fuel Sender Assembly Replacement in the Service Manual.
NOTE:
Ensure that the fuel level sensor pigtail wires are routed through the anti-chafing conduit of the fuel sender assembly to avoid damaging the fuel level sensor pigtail wires. Route the fuel level sensor pigtail wires through the anti-chafing conduit the same way the wires were routed in the old fuel sender assembly.
6. Remove the fuel level sensor from the old fuel sender assembly and install it to the new fuel sender assembly. Refer to Fuel Level Sensor Replacement in the Service Manual.
7. Install the fuel sender assembly into the fuel tank and install the fuel tank. Refer to Fuel Sender Assembly Replacement in the Service Manual.
