doesnt sound good, running really rough
the other day i was driving aroung doing erins everything was fine, went home for a bit the had to run back out only this time when i started my truck up it was idling quite rough and when i put it in gear and started to move it was almost missing, so i left it, went away for the weekend and finally got to look at it today and now it struggles to stay running at idle and bareley revs, hope its not injectors, cant afford that right now. it was dumping rain the day it happened but its been a week since of warm weather so i cant see it being water problem, but i dont know

I'm not the brightest when it comes to rough idle/starting problems, but i know when i did my turbo upgrade, the harness on top of the valve covers got pulled just ever so loose and made it idle rough. Might try and see if they're plugged in all the way. Someone with a better understanding will chime in. Just a thought tho

1. Check oil level.
2. Check tin nut on back of IPR.
3. Get codes read.
4. Unplug ICP, not remove and see if idle is better.
5. Make sure fuel filter is good and fuel is flowing.
6. Check UVC connections.
7. Report findings back and we'll go from there.

im having a brain fart, what are the UVC connections again?
and is the IPR the object on top of the HPOP where the fuel pressure spring is located?

k so i tried starting it today and now it wont start so i opened the fuel bowl and it wasn't full, i drained it on the back to get rid of any water but now it wont fill back up when i cycle the key on, the pump on the frame rail is working but it sounds louder than usual like its sucking air, i was thinking maybe my guage is faulty and that i ran out of fuel so i put in a few jerry cans of diesel and the gauge went up so it should be fine but im still not getting fuel to the fuel bowl.
any ideas?

It will take several pump cycles to get the air out. You really need to be over 1/4 tank full. Cycle key on and off for 20 seconds for at least 3 to 4 times. It should prime itself.

How much fuel is in the tank? How dirty does your fuel filter look? Have you tried pouring diesel in the fuel filter bowl to see if that helps prime the pump? You can also remove the fuel line off the back side of the fuel pump, then blow some low pressure compressed air into the tank to get the fuel flowing, or stick a small hose on the back of the pump and dip it in a container of diesel to get fuel flowing through the lines.

i tried cycleing the pump on and off several times over and over but nothing fills into the bowl, ill try the hose on the end of the fuel pump to prime the lines tomorrow and see what happens, and ill try blowing some air in the line back to the tank to se if i can dislodge anything that may be in there.
