2002 Volvo x70cv. Bought it about 2 weeks ago. From the start I had to hold the key for a couple seconds for it to start. Sometimes would take 2 attempts. I went to start it this morning and after about 6 tries it started for about 4-5 seconds and died. Now it won't start at all. Turns over fine. Also there has been a faint smell of gas around the car. I cannot find any leaks and no drips in the driveway. Just smells. Would this possibly be the pressure regulator or the fuel pump itself? Any and all input is greatly appreciated
