Question about 1997 Honda Civic
My fuel gauge is stuck on either full or empty, fuel level has no effect on the position, it is just random. I'm just throwing a shot in the dark to see if anyone else is having a problem or seen a problem like this before.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Well, theres a sending unit/float in the tank that sends a signal thru
wires to your instrument cluster's fuel gauge. You should have an auto
electric repairperson determine where your problem lies. It's not often
the needle's just 'stuck' to where you could dislodge it. More often,
it's pegged overfull or underempty-signaling a shorted component
upstream of the gauge.
Similar problem and found the solution:
In the back of the gauge, where the 2 coils are located, there are very tiny copper wires which connect all the resistors/diodes. they each travel from within the coil and are soldered to 3 out of the 4 mounting pins. if any of these wires are shorting out or disconnected, the gauge will malfunction.
- take the gauge and flip upside down
- temp gauge has 1 resistor (blue) and 1 diode (copper)
- fuel gauge has 2 resistors, no diodes
- 1 wire should be attached to bottom mounting pin (letter E for EMPTY)
- 1 wire should be attached to pin holding both resistors (half tank)
- 1 wire should be attached to the stand-alone ground pin (no mounting bracket)
Hope that helps!

more likely the fuel gauge in the dash is the problem, you can check this by taking the rear seat out to get to the fuel sending unit, then disconnect the connector while you have the ignition on and see if it change.
if it changes the sender is bad, if it doesn't the cluster is bad.
