6.0 intermittent no crank and Limp mode

Hey guys Im new to 6.0 so take it easy on me if I ask silly questions.

03 6.0 studded and deleted, It will start about half the time, and half the time it will not even crank. Pulled codes and it says its failing pre-check but won't tell me what is failing. I has a couple other codes, cylinders 1 and 3 have a code that says something like its not getting fuel, blanking on what exactly is says right now. And KAM code. So once it starts it idles rough, and when you drive it the truck will only go about 50mph tops floored. I put it on the trailer last night and would barely drive up the trailer Pic for your fun.

I have a list of things to check but if you guys have any more suggestions that would be helpful.

Things to check, EBP, ICP, FICM, IPR, MAP, Fan Clutch sensor. Anything else?

fuel pressure and check all power connections. if it won't crank then you could have intermittent power issues, batt cables etc. get a reading on what you have listed and go from there. Don't guess cause that gets expensive.

Alright, just got done checking the FICM, it's pulling 48V but it's a 4 pin on an 03. I thought 03 and early 04 had 7 pin. Would that be causing the problem

Ok guys did a little more digging, FICM is from a late 04+ and is sending the right volts. From what I read that is ok. Not the fan clutch, not the ipr. All connection look good, it fired right up for me today but still had low power. Fuel filter looks old will replace tomorrow. I'm calling it a night but here are the codes.

P1000
P2269

Any help would be great thanks agin

Here is what it's doing, when I put it in reverse I give it full throttle and that's all it's got. Then in park it revs right up.

I had the same issue turned out the stupid mechanic that I bought the truck from left one of the boots off the driver's side lower intercooler pipe. New clamp, reattached the boot, and all the boost I can handle for now until I start doing upgrades.

I bought all new Riff Raff boots and put them on, I thought it was that at one time.

Hey bud!

Do you have a code reader?? can you pull codes?? After that I would check fuel pressure.

I do have a code reader, had it hooked up to mine and a really nice snap on tool and still no codes. I have checked both fuel and oil pressure and they are good at idle and under load.
