already unplugged the chip no change at all, before i installed the chip it still idled rough due to single shot injectors in a split shot truck but the new ts chip is programmed to run the single shots so with 2 dead injecors im stumped, i am going to try and stick one of the dead injectos in another hole and se if its maybe the harnesses and uhvc i just replaced then tomorrow im going to ohm the idm harnes

no need to remove/install injectors in different holes. Swap the connectors at the injectors, see if it follows the injector/s or not / swap solenoid atop the injector.

Time to get on some diagnostic software, try cleaning the IPR if you want,( you didn't say how you knew the IPR and ICP are good) but it needs to be properly diagnosed, not " it sounds like". Sorry, other option is to start replacing expensive parts by the flip of a coin. See if anyone in your area has AE software.

check your torque on the two dead cylinders. When i did my injector swap, i had a couple injectors that were not torque down all the way and caused dead cylinders, I re checked everything and retorqed it all and bam all my cylinders came back to life

also, at idle, get a temperature gun and shoot it at the manifolds, to their respective cylinders. See if theres a change in temp.

there is no need for me to check the manifolds with a temp gun as i already know which cylenders arent firin (have vc's off andunplugged injectors on both sides one at a time) but update my brother (diesel mechanic) said his boss is having the exact same problem with his truck they changed harnesses (entire harness from idm to injectors)they tried a new idm but still no change, they finally discovered that it was the fuel pump on the frame wasnt putting out enough pressure to feed all the injectors, so tomorrow i am going to replace the fuel pump and hopefully hat is it.

- Really??
Is that the way your brother (the "mechanic") diagnoses a problem? I hope not for his customers sake

Did you try an IDM? (the most likely cause) A Buzz Test? ANYTHING I advised in your other post on this?

Why wouldn't you simply put a gauge in the fuel port, if you suspect low pressure, instead of replacing, what might be, a perfectly good pump?

You really need to learn how to diagnose a problem instead of your "Throwing Parts" approach. Who exactly advised you that the way to test an IPR was to just unplug it and see if the engine runs or not? -LOL

If the engine doesn't start the IPR must be 100% huh? I hope you have DEEP POCKETS to continue. If you had any sense, you'd spend for an AutoEnginuity and learn how to use it
