FUEL GAUGE REGISTERS EMPTY WITH FUEL IN TANK
The fuel gauge on some 1984-1986 Cherokee/Wagoneer vehicles may register empty or below when there is fuel in the tank. If the vehicle is a 1986
model with a 2.46L engine, this may be accompanied by a no start condition.
This may be due to the body harness (A) breakout that routes through the floor grommet grounding out against the rear floor cover support (B). Service
correction involves repairing the wiring and modifying the rear floor cover support.
