I changed my fuel tank , filter and fuel pump seal and I stop have the same issue. I also only 240miles on a full tank. It guzzles gas like crazy, and smelling strong gas fumes come from the rear passenger side of my car. I don't have a check engine light cause the car passed emissions with flying colors. My I boughtthe fuel cap from the dealer and it's the same problem. The tank just won't pressurize!! What should I do? I really need some help.

    Check your vapor recovery system. Start with the filler neck (these have a tendency to rust out) and filler hose for cracks and wear. Check all hoses in system. Or, go to a shop equipped with "smoke test" equipment to find this apparently large system leak.

    Had all of that done already too, and came up short. Could it be a bad fuel pressure regulator?

    Had codes pulled and nothing came up. I even realized yesterday that it had a lil trouble starting. Could it be my fuel pressure regulator?

    Need fuel pressure test to be sure, but it could be the regulator.
