How do you know if the fuel system fuse is bad?

To determine if the fuel system fuse is bad, first check for any signs of electrical issues, such as the fuel pump not activating or the engine not starting. Next, inspect the fuse box for a blown fuse, which typically appears discolored, melted, or has a broken wire inside. You can also use a multimeter to test for continuity; if there's no continuity, the fuse is likely faulty. If the fuse is intact but the fuel system still isn't functioning, further diagnosis may be needed.
