i drove to my apartment 3 days ago to turn in my 30 day notice and pay the months rent. went back out to the truck to start it and no luck. the truck turns over, fires up for about 2 seconds and dies. when it starts the rpms go up to about 2000 is all then the truck dies. if i try to give it gas when its started for the 2 seconds it only makes the truck die faster and the rpms dont go up at all when i hit the pedal. i had about 40,000 miles on the fuel filter so i changed it in the parking lot where the truck sits hopeing maybe i wasnt getting enough fuel pressure through a clogged filter. once i changed it out i tried to start it and it just did the same thing as before. when i turn the key forward i can hear the pumps turn on. i left the key forward and popped the hood. i took the cap off of the valve stem on the fuel rail and pressed it down with a screw driver and didnt get any fuel coming out at all, just the sound of air like from a tire was all. i dont have a fuel pressure guage so i dont know what its at. im thinking maybe one of the hoses came off of one of the pumps in the fuel tank maybe. i installed dual 255 pumps about 8 months ago. the first night i had problems i hooked up the predator and got a fuel code. it said something along the lines of #2 fuel circuit high. i cleared the codes, un hooked the battery and hooked it back up. tried re-uploading my tune and starting the truck and it still wont start. now i cant get the code to come back up so i cant write down the exact number that it gave me the first night. my truck has been sitting for 3 days now 30 minutes away from my house and i have been haveing to drive my roomies car back and forth until i can figure out what to do with it. theres only one shop thats big up here on fords and because of that they think they can charge 150% more then everyone else so im not taking it to them, and i dont feel like taking it to a dealer to see whats the problem with it. anyone have any clue as to what it might be causeing me the problems with not wanting to stay running once started????
