A leak detection pump can fail over time. Signs that it may need replacing include a check engine light with EVAP leak codes or leak detection pump codes, or an EVAP readiness monitor that won't complete. Loose gas caps, cracked hoses and other EVAP components can set similar codes, so confirm the cause before you replace the pump.
