so, the gas gauge on a buddies fj40 does not work. as I understand it, there are only 3 reasons why (let me know if there are more).
so, without spending a bunch of money and wasted time, how do you best determine what the issue is, then get the part/fix you need?
- 1. bad wiring = loose, cut, old
- 2. bad gas gauge at the dash
- 3. bad relay switch
