All gauges go to full, there may be a short circuit somewhere instead of the limiter being the fault. Modern regulators have built in protection that turns them off when there is a fault downstream. Diagnosis is key. Something simple, Disconnect the temp sender and see what fuel gauge alone does. Then disconnect fuel sender and try temp gauge alone.
Since the later model wiring harnesses are plagued with issues, the fault could be most anywhere. 1 possibility is the white plastic engine harness connector. They routed the alternator wires through here with several others. Those connectors melt and create all sorts of crossed circuits. Good luck
