To troubleshoot the fuel pump on a 1990 Mighty Max, start by checking the fuel pump fuse and relay for continuity, as a blown fuse or faulty relay can prevent the pump from operating. Next, test for voltage at the fuel pump connector while turning the ignition key to the "ON" position; if there’s no power, trace the wiring back to the fuel pump relay and ECU. If power is present, use a fuel pressure gauge to check if the fuel pump is delivering the correct pressure; if it’s below specifications, the pump may need replacement. Lastly, inspect the fuel filter and lines for clogs or leaks that could affect fuel delivery.
