My Jeep is acting weird. When I go to start it after its sat for an hour it takes a lot of time to her started. And when I start to go it hesitated so bad it almost dies then sorta pops out of the intake. I don't think my fuel line stays primed. If it sis and I hit the fuel pressure button it doesn't shoot out. Could it be a vacuum leak our the regulator that is on the driver side fuel rail? Any help would be very appreciated!
