Hi All, Got a problem with a seat arosa 1.0, keep getting error : fuel injector ground to earth and lamda sensor ground to earth, This is causing the car not to start either for a few hours or a few minutes, but if i reset the fault with the reader it will start straight away, i have cleaned the front oxygen sensor and replaced the lamda sensor and done a service, i noticed the fuel pump is priming intermittently, could this be the fuel pump relay?
