I have a 2015 Chevy Silverado 4.3 and it stalled and has the code PO232 & PO23F. No fuses blown. It would randomly fire but would die soon after. I replaced the fuel pump and found a shorted wire at the pump itself. Replaced and runs as normal with no check engine light but it is still showing the codes . I will delete the codes with a scan tool and then without even cranking it over the codes will still show. Even disconnected the battery and the codes are still present without even turning the engine over. I need to smog it and any advice would be much appreciated. Thanks in advance
