We gotta get that figured out now. That could be the whole problem. The ECU is expecting something else. Unplug the sensor. I'm not sure it's needed to run. It may go into a limp mode, but that's OK. It'll come back out. Make sure the wiring didn't get torn or pinched too.

I fully intend to. Gotta figure out location and what it looks like in this rig. But sadly i wont be able to touch her til tomorrow. Shes at my folks because my apartment complex will pentalize you for working on a vehicle. And the bus dont run that far from where i work. Haha

unplugging the sensor will help with diagnostics. if you have, or can borrow a gauge would help as well. do you notice any difference in how it runs compared to before, or compared to another near identical truck at idle? Does anything sound off? A good ear will also tell you a lot. I am leaning towards bad sensor, although that would usually throw a code along the lines of "rail pressure (value returned) greater than expected" but not always. is there any chance any contaminates got into the lines or rail when injectors were changed?

F350cummins and I talked about you at supper last night. He was here. I'm leaning towards the same. But you call it when you said you fixed a tube. I'd go over all of them.

I kept the area clean as possible. Wasnt windy or dusty either.
I have a p0148 which is basically that code. Fuel rail pressure deviance from set point. I get out of school at two, im going to go home and try that. If that fails though, im without anither option but to bring her to the shop. Its too hard for me to get over to my parents to work on it in the time i need it finished. (Dont know if i mentioned but i live in apartments where they fine you if you work on your car. So shes at my parents three cities away.
