Fuel Gauge
- Locate pink wire near trunk latch and disconnect. Gauge should register above full. Connect a good sending unit to pink wire, and ground body of unit. As float arm is moved, gauge needle should follow.
- If gauge does not follow sending unit movement, inspect wire between gauge and connector at tank. If gauge is stuck in full position, check for open or broken wire. If gauge is stuck in empty position, check for shorts or grounded wire. If all connections are good and no wire damage is found, replace fuel gauge.
- If fuel gauge operates properly with substituted sending unit, check ground connection of existing tank sender. If ground connection is bad, repair. If ground connection is good, lower tank, remove sending unit, and test with ohmmeter. Resistance should change smoothly from 0 ohms at empty to 88-92 ohms at full. If not, replace sender.
