lazy cummins???
Do a search for "fuelplate", that´ll be a help, or maybe not, if you´re having problems getting fuel now, asking for more won´t help any.
I´m with Gorms on the air in the fuel, and the prefilter was my best guess, but if you don´t have one that can´t be it.
Maybe it´s time for a new fuelhose, from the tank to the liftpump, then you know that´s not bad.

i looked on the p7100 thread and i see part 89 and you just push that in the most forward position? do you need to turn up the boost of advance the timing never done this before just want a good clear explanation of whats going on before i do it thanks in advance
Yes, you just push it forward, if it blacks out the mirror you went too far and should move it back some, or put a boost elbow on it to get more turbo pressure.
And so it begins
...
And get gauges, turbo pressure, fuel pressure and EGT, no need to mess it up just because you get "all funny" tweeking that pump LOL.
And be careful, I don´t know what transmission you got, but I know I´ll stay out of my pump untill I get mine fixed, I´m pretty sure I´ll get all carried away once I dig in...and I don´t want it to blow up.
You might wanna do a search for "starwheel" as well.

is there any way of testing injectors??? the truck works ok but not as good as my other truck and at low rpm under 1000 it seems like it has a slight skip but bump the throttle up and it comes out of it any one have any input?
Run a tank heavily laced with a good additive like Power Service, probably 3X the recommended strength. That will usually clean them up if it is just some filth.
well finally got around to it today and moved the fuel plate forward and i really didnt expect to see any amount of power man was i wrong whole different truck hauls *** might start drag racing at the lights with the 5 ton lol still sounds like a miss at idle but doesnt seem to affect the performance
The spec for your engine is printed on a plate that is attached to your engine.
More specifically, it's on the driver's side of the timing gear case/housing. Standing next to the driver's side fender with the hood up, look at the injection pump where it meets the gear case. There will be a data plate there with the correct specs.
