Starts But Than Runs Like Crap, and Dies Out

[lifted125r]

Hey guys, i got a 96 f350 PSD i got a few mods done to it. What happened was that i was driving down the street and all of a sudden the thing just started boggin down, i pulled over, and it came back to life, then i drove a little more and it started doing it again. It is to the point now where when i start the truck it usally will start up normally-- but by the time i get it into drive, it just starts sputtering, and the ideal dies out. I tryed unpluggin the chip to see if that fixed it but it did not work. It sounds like its not getting fuel, but i took the fuel filter out, emeptyed it, and turned the truck back on with an exmply set up in there, and it started up, and it filled back up with fuel. I changed the CPS but that did not do anything. My fuel heater has been broken now for about 2 mouths, i just had to replace the fuse and had unpluged the heater, but i dont think that has anythign to do wiht it. Any ideas, i am loosing my mind? thanks, ryan

How dirty was the fuel filter? Not sure if I have this correct but you are saying it ran fine without the filter?

Welcome to Powerstroke.org

Did you change the filter, or just remove it??

What about checking your oil? The HPOP takes oil to make the injectors work. Might be enough when everything is drained down at start up, but once it starts to pump oil through the rockers, etc, it might be running out.

Just a couple of guesses and a free bump.

HOW LONG SINCE YOU CHANGED YOUR OIL POSSIBLE OIL AERATION.WHAT IS YOUR FUEL PRESSURE?

No i put the fuel filter back into it, with an empy bowl, to see if the bowl would fill back up- and it did. I just changed the fuel filter, changed the oil. Went to start it up, tooka few cranks, than started up and ran perfect. However after about 30 seconds of it running good, it started to sputter and near stall out, the entire truck was just like shaking etc, and now it is doing it again consistanly.

Also yesterday, i did build a new exhaust on it, a 4 in out under the cab with a 3 in down pipe (down pipe was on previously). I dont think that woudl have anythign to do wiht it thou. However when i did weld the brackts onto the exhaust, i did not unplug the battery.

Passenger side wiring harness under the valve cover? It just sounds like what happened to me when mine went out.

i pluged it into a snap-on computer and got P0113 says intake air temp circ high input. i know that that is that sensor, but there is no way that that sensor for air temp is causing my truck to run like its depreived of fuel and keep stallin out. I also just swaped out the injector module computer to see if that was it, but it did the same thing. Any ideas?

If you have a snap on scanner I would run a injector buzz test to see if it might be the uvc harness.

I don't really have any ideas except you could have burned something by not unplugging your batteries and wire feed welding on it.
