Exclamation Early 99 Hard start, rough idle, no power. Codes inside.

Hey yall, been laying low for a little while but now im back for more punishment lol. I been having a problem recently with a service truck i recently got. Its an early 99 single cab 4x4 with about 253k on it. Been sitting for awhile so i started with fresh fuel and filter, and bled out what i could with some fresh fuel and howe's. Looks like a mix of heating oil and diesel and some other fun stuff came out... it was nasty and def needed out of my tank. Below is a video of whats going on with it. Basically it starts a little hard, runs super rough, and has NO power. Like will not run over a pebble. It spent its life as a rock crusher and screener service truck, so its had some off road abuse. Ive checked under valve cover harnesses and and plugs and its free of fraying or breaks, and has continuity from the outside to the injectors. I also did a buzz test and all injectors buzz and pass with no codes, but another mechanic has told me that, even with buzzing they can still be bad. doing koeo test the only code i constantly get is p0603 or Internal Ctrl Mod KAM Error, not sure what this means... In continous memory i get p1219 Cylinder ID low, and p1298 IDM failure. There is also a junkyard turbo on this truck, and i was told this was replaced about 50k ago.. The PCM to IDM harness appears fine, with no obvious distress or fraying or wear. Im not sure were else to go... Ive done a buzz test, when i try to do a cylinder contribute test, it dies. I get a few oddball codes when i do KOER test, but its all body stuff, nothing powertrain related.

Im open to any and all Ideas. Like i said, where the truck acted as a rock crusher and screener service truck, its had its fair share of offroad abuse... so computer failure (IDM) is not out of the question. Im open to any and all ideas. I guess my next step is test compression, cause if it had a junkyard turbo on it, something most likely got into the intake and wasted it, and hopefully didnt waste the motor, it does crank like it has good compression though. I havent checked the ICP sensor, but im not sure if i should cause its not showing up on the codes, even though we should treat the symptoms and not the computer...

Please somebody help me before i go insane!!! i cant take this carrying tools and what not in my pickup.. thats wat the service truck is for!

Thanks in advance,

My truck does the exact same thing as yours! Has become a huge pita. I have replaced:
Fuel Filter-at least 4 times
Oil Filter-at least 5 times
Air Filter once- needs again have K&N thinking it needs to return to stock
Icp Sensor
Cmp/Cps - whatever it wants to be called by whoever manufacturer
EBPS Sensor and Tube
Injectors #8, #7
Borrowed a scanner read the codes myself came up with #7 injector went to cheap mechanic to have it fixed he screwed it up needless to say we have been in and out of the dealership 3 times since and the truck is still not right. Compression is good Turbo pushing 18psi and still no fix Good Luck hopefully you find the issue I'm going to subscribe.

HPop was replaced last year so we've ruled that out as an issue. Someone replied on my post and said to check the sock on my in-tank fuel pump and the screens inside filter housing. That is what I'm doing tomorrow
