When do the fuel gauge lights come on?
Ignore the “2-wire” fuel gauge stuff – that circuit design was only used for the ’63-’67 Corvette and a few Cadillacs of the same era. Quick update on this When I jumped the ground to both console gauge pod metal plates, I now get the all Four gauge lights come on BRIGHT – as in full on – when the ignition key is turned to he “ON” position.
What causes a fuel gauge to read empty?
Another common symptom of a faulty fuel gauge sender is a gauge that is stuck on empty. If the float somehow breaks or becomes separated from the arm it may cause the fuel gauge to malfunction and become stuck on empty. A faulty resistor can also cause the gauge to read empty. 3. Fuel gauge stuck on full
Can a bad fuel gauge sender send a bad signal?
Another, less common, symptom of an issue with the fuel gauge sender is a fuel gauge that is stuck on full. A faulty fuel gauge resistor can send a bad signal to the instrument cluster which can cause the gauge to permanently read full. This is an issue, as the driver needs to know the accurate fuel level of the vehicle as to not run out of fuel.
What should I do if my gauges are not working?
The first step in diagnosing this type of issue is to identify the fuse associated with the instrument cluster or gauges. The fuse should have power on both sides when the ignition key is turned to the on position.
Why is my fuel gauge not working properly?
Fuel gauge troubleshooting begins with isolating the problem either to the gauge, sending unit, fuse or wiring. The most common gauge problems are either a bad ground at the tank, or a sender problem.

What to do if your coolant gauge is not working?
Using your coolant temperature gauge as an example, the diagnostic procedure involves locating and disconnecting the sending unit. With the ignition on, the gauge should register cold. If you connect the sending unit wire to ground, the gauge should switch to read hot.
