To fix a faulty fuel pump, start by checking the fuse and relay. If they’re working, inspect and clean any clogged fuel filters. If the problem persists, test the pump’s voltage. A multimeter can help determine if it’s receiving power. No voltage indicates an electrical issue, while voltage without performance suggests the pump itself needs replacing. Always consult your vehicle’s manual and follow safety guidelines to prevent accidents.
