Inoperative Fuel Gauge and Hard Start/No Start Condition
June 18, 2012
Some 2008-2012 Enclave, 2009-2012 Traverse, 2007-2012 Acadia and 2007-2010 Outlook models may exhibit one or more of the following conditions:
• Engine is hard to start • Engine will not start • Engine starts, then stalls • Fuel gauge is inoperative or fluctuates • Service Engine Soon/Check Engine light is illuminated
These conditions, which may be intermittent and have various DTCs set, may be due to the fuel tank harness to body harness retainer slipping on the tubing, putting pressure on the harness and causing connector X305 to become partially separated or not fully seated. (Fig. 13)
Inspect connector X305 to make sure that it is fully seated. If the connector is not fully seated, inspect the terminals at connector X305 for corrosion. If the terminals show signs of corrosion, replace the corroded terminals.
Remove the wire harness retaining clip from the steel lines (Fig. 14, Position 1) and reposition it in front of the steel line support to prevent it from sliding. (Fig. 14. Position 2)
