To fix the gas gauge on a 1990 Mazda Miata, first check the fuse related to the instrument cluster to ensure it's not blown. If the fuse is intact, inspect the fuel sender unit located in the fuel tank for any faults or debris. Additionally, verify the wiring and connections between the sender and the gauge for any signs of damage or corrosion. If these components are functioning properly, the issue may lie within the gauge itself, which may require replacement.

first thing is to work out which part is at fault? I would start with dash gauge, find wire at fuel tank which goes to gauge, earth this wire out to body while having friend watch fuel gauge, if it goes straight to full it mean dash gauge is good but sender unit in fuel tank is probably at fault. Go to car wreckers for s/h part.
