My 2015 Infiniti Q50 wouldn’t start one afternoon. And upon trying to start it . My car would shake then immediately turn off. I’ve taken it to my mechanic and he replaced the fuel pump. Three weeks later the same problem arose. Frustrated with the whole situation I had to tow my vehicle back to the mechanic shop. Then he stated that I have to replace the fuel pump harness connector.(mind you the dealership doesn’t carry the item) Please help . I need help find a fuel pump harness connector or an alternative method.
