Why is the Fuel gauge always on empty and the warning light on. 1992 Volvo 740?

If the fuel gauge in a 1992 Volvo 740 always shows empty and the warning light is on, it could be due to a faulty fuel level sensor in the fuel tank or a malfunctioning gauge itself.

If these steps don’t work, a diagnostic inspection may be needed to pinpoint the problem.
