Had fuel pump replaced then bought manufacture gas cap replaced relay 3 weeks ago now gas cap light is popping up engine light is on and is running worse everyday please any advice would be great
It might be a large vacuum leak in the EVAP system. Large vacuum leaks will throw this code and might cause erratic running, as it leans out the fuel mixture to a point where the ECM cannot compensate.
Smoke machines are often used to detect and fix EVAP system leaks
You could also have a fuel tank leak, which is possible given your recent fuel pump replacement
Also the EVAP canister fuel vent valve could be inoperative.
