Hello, the fuel gauge is most likely an issue with the fuel sender float, when they go bad it reads open and a full tank on the cluster. But the other issues may or may not be related. it would be best to check the basics first, check all fuses for the instrument cluster. Inspect the wiring to the fuel tank/fuel pump. A diagnostic check for codes of the instrument cluster would need to be done to see if it has its own faults stored. This would require a high end or dealer style scan tool. Most codes readers only check engine codes only. So if the basics check out ok, a diagnostic would need to be run. Its possible the insturment cluster itself is failing and would need to be replaced, which would require reprogramming by a dealer scan tool and 2 PATS ignition keys reprogrammed to start the car.
