Cody here are my results,
my truck for some reason wont give me the info you want, I tried 3 scanners and the 3rd scanner was expensive and had 7.3 data installed. here are three pics of the scanner.
Also I ordered a icp sensor need my truck bad!!

Eric,

Being that unplugging the ICP sensor and driving the truck still got you the same results, I doubt it's the ICP sensor causing your problem. The last thing I wanted to have happen was to have you start throwing parts at the truck in an attempt to accidentally fix the problem. Unfortunately, the data you have there isn't helping anything. Throwing parts at a truck is a sure-fire way to spend a lot of money and not get anything accomplished. I realize that you need your truck and neither Bill or myself are happy that you're having problems right now.

I am still leaning toward the Injector Pressure Regulator on the back of the high pressure oil pump, but without actually being able to test out what I need to see, it's not possible to diagnose the problem.....and DON'T THROW ONE IN JUST BECAUSE I MENTIONED IT!!

Have you removed the chip and tried it? That was Bill's next thought. Drive it around on the factory programming and try it.

I am changing the icp because when I pulled the plug there was some engine oil on the plug. What I was reading stated if you saw that it was going bad. I promise I won't buy any more parts! I will unplug the chip and try that.

I tried that and nothing different happened. Do you and bill remember my computer problem I had were we couldnt find the code on it. It was xx do you think maybe that has something to do with this.

Nothing different happened....What does that mean? Does it mean that it still hesitated and tried stalling with the chip removed?

Nothing would be affected other than a check engine light due to improperly working glow plugs (due to your truck having a glow plug module) if you were sent the wrong PCM code......and you have no diagnostic trouble codes so we won't even worry about the wrong calibration code.

Nothing happened meaning the code reader did not pick up any of the sensors. When I unplug the chip it runs horrible because of the single shot stage 2 injectors so I could tell a difference. BUT I got an update Cody.
I took out the ipr regulator and cleaned it,

There is the link I found. Here is what I found.
The round magnet thing was not bolted down on the ipr regulator. It was just sliding back and forth. So would that cause an issue? I pulled the reg. Apart and cleaned it. I searched and found a pipe reducer that fit on the screw part on the reg. So I re installed the regulator put the magnet thing on, a bolt to take up space, and then tightened the reducer to hold everything into place. It's ghetto but it works. I drove down to auburn (430am) and back and no hesitation. Its still cool out so this evening i will drive it to test in the heat. Hopefully its fixed. Any comments?
Going to bed been up all night! Nighter
