Can be fuel tank sending unit or dash fuel gauge or wiring in between or just a bad ground on it.
I always take a old bulb type test light and hook one end to ground and probe the purple wire to fuel pump sending unit.
Key on.
If test light lights dim and dash fuel gauge swings to full.
Yor fuel tank gauge or wiring to it or ground is bad.
If not check dash fuel gauge and wiring and plugin and printed circuit.
Good luck
