I went to start my vehicle and it started turning but never started. After a few tries it started and then completely went out every time. I haven't been able to use my vehicle for almost a month now. I got 3 different mechanics to look at it and they still weren't able to get it back working and I all they could tell me was it had something to do with the fuel pump and the high pressure pump.
