The fuel gauge may work erratically and/or the vehicle may not start. This may be caused by the fuel tank sending unit wiring connector becoming loose and/or corroding. This looseness and/or corrosion may be caused by the lack of a locking mechanism on the connector.
Install a new fuel tank sending unit pigtail connector to the existing wire harness. The new pigtail will provide improved sealing and a positive locking mechanism to reduce the possibility of looseness or corrosion. Refer to the following Service Procedure for details.
- Disconnect the negative battery cable.
- Remove the fuel tank following the procedure outlined in the appropriate Service Manual, Section 10-01A.
- Remove the old connector from the fuel tank sending unit.
- Cut the connector off of the vehicle’s wiring harness about 152mm (6″) from the old connector.
- Install the new connector, matching the wire colors and using “Duraseal” butt splice connectors. Refer to Figure 1.
Figure 1 – Article 97-9-15
- Using a heat gun, seal the splice.
WARNING: DO NOT USE AN OPEN FLAME TO SEAL THE SPLICE.
- Reconnect the fuel tank sending unit wiring connector.
- Reinstall the fuel tank following the procedure outlined in the appropriate Service Manual, Section 10-01A.
- Reconnect the negative battery cable.
