my gas gauge isn't working

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! If you've replaced both fuel pumps (which include the sending units) twice, and the gauge is still acting up, then yeah, the instrument cluster could be the culprit. But before blaming the dash, check the wiring and connections between the fuel sending units and the body control module (BCM). A bad ground or corroded connector can cause erratic readings. Also, some Chargers have had issues with the BCM misinterpreting fuel level data—a software update from Dodge might help. A scan tool that reads live fuel level data can tell you if the problem is in the tank or further up the chain.
