Ok, it has a new fuel pump... so I can pretty much rule that out... I did however have some serious pressure inside the tank once, another time I found a vacuum leak that seemed to fix the problem, another time, I found a leak from the Heater valve that seemed to fix the problem. The code 44 dissapears after a few minutes, or after I jump on it, sometimes no code sets when it runs like "poopey". It only does it after 150 miles of highway driving! I can drive around town for 6,000,000 miles and it's fine. (exagerated of course) It seems to make no difference where the fuel is, as it's been almost empty and almost full when it did it, only after 150 miles of straight driving. I am going to drive 149 miles and then directly into a brick wall very soon. Thank you.
