What would cause fuel gauge not working on 1991 dodge dynasty?

A non-functional fuel gauge on a 1991 Dodge Dynasty could be caused by several issues, including a faulty fuel sending unit, which is responsible for measuring the fuel level and sending the signal to the gauge. Additionally, wiring problems, such as damaged or corroded connections, can disrupt the electrical signal. A malfunctioning gauge itself or issues with the instrument cluster could also be contributing factors. Lastly, a blown fuse related to the gauge circuit may be the culprit.
