...eventually starts? This problem started coming up about a month ago, and wasn't a serious problem till I went on a longer drive then usual, and noticed the mileage computer saying I was only getting 14 miles/gal when I was cruising at 60 mph. It is usually at about 20-21 miles/gal. I also noticed when hitting the throttle that it would rev up real high when I only tapped it. Now every time I go to start the Jeep it has trouble starting, sometimes it makes a high pitched sound and doesn't start, then it just bogs and starts.I was wondering if someone could help me out with this dilemma and hopefully it isn't the fuel pump.
