Some models have a in line fuse in the wire going to the starter follow the wire from the starter if you find a larger section in the wire that's it ck for power on each side of wire with a probe if you have power on one side and not the other then the fuse has blown
What symptoms? There is no fuse that I know of. The starter either works or doesn't. Does it click at all? First eliminate a dead battery. How many volts does the battery have? It needs 13.8 to start a car.
