Oil fuel gauge not working 89 Pontiac sunbird?

If the oil fuel gauge in your 1989 Pontiac Sunbird is not working, it could be due to a faulty sending unit, a bad gauge, or an issue with the wiring. Start by checking the connections at the sending unit and the gauge for any loose or corroded wires. If those seem fine, consider testing or replacing the sending unit and the gauge itself. Consulting a repair manual for specific troubleshooting steps can also be helpful.
