    Fuel delivery issues

    So my car was rather low on gas the other day, to the point where it was sputtering as I drove the half mile to the gas station. I got there, filled her up and was expecting the sputtering to go away, but it didn't. So I drove it home and parked it. I figured it sounded like a fuel pump issue so I replaced the in tank pump with one I know is working, but it didn't fix the issue. The car will will die when just idling and when you press the gas it will just sputter for a few seconds then rev up. When driving at about 30 mph it will do the same thing, it acts like it's not getting fuel, it sputters and doesn't accelerate.

    (I changed the cap and rotor, spark plugs, and wires a few months ago, also its pulling plenty of air when i rev it up.)

    So, I don't want to replace the external fuel pump if that's not the issue as they are 150 bucks.

    But i'm not sure what else it could be besides maybe the fuel filter is clogged up?

    Any help would be great, I want to get it fixed, just don't want to throw money at it.

    Appreciate the help!

    You could have run your tank low enough that your fuel pick-up sucked in sediment off the bottom of your tank. You already changed, the fuel pump... did you clean the fuel pick up screen? I would also replace the fuel filter, as you mentioned in your initial thread, as it may be clogged with sediment. You may want to check out jlevie's threads about the acid/POR 15 treatment for tank sediment repair. It is labor intensive, but cheaper than a new tank.

    In the interim, as a precautionary measure, I would always keep at least 1/4 tank of gas in the car or more.

    Hope this helps and good luck.

    Note: I just re-read your post... check your fuel pump and listen for the whine of death. It still could be a weak fuel pump and sediment running through a fuel pump will takes it toll over time.

      I put a new screen on the in pump tank. My car has two fuel pumps. I only replaced the intank pump.

      Yes, the pump outside the tank has been loud for the whole time i've owned the car (year and a half), but not really "whiney" But I haven't had any issues, even running the car low on fuel.

      I was thinking maybe the filter was clogged up and because its only 20 bucks I was thinking I should replace that first and see if its the issue. I don't think I have much sediment in the tank, the filter on the pickup pump was rather clean, and I couldn't see any when I looked down in the tank. But, who knows.

        The hesitation coming off idle sounds like an intake leak more than a fuel delivery problem.

          I guess its hard to get over that i was almost out of fuel. Even though correlation isn't causation.

          So check for vacuum leaks?

            Here is a video of what it's doing. It is sputtering even with gas, and will shut off if just turned on.

            I am getting fuel pressure so I don't think it's the pump. I'm just not sure what to do.

              The behavior in the video suggests that intake leaks are a distinct possibility. A smoke test will tell. I doubt that the car is drivable, so it probably needs to be towed to a shop.

                I've come to that realization. I am going to do that today.
