RE: Hello Everyone HELP PLZ
NO START
What causes ipr 65% and icp 2400/2600psi while cranking?
99 f350 New IDM,fuel filter,icp,ipr,uvhc and pigtails,glow plugs,GPR,high torque starter. Engine and hpop oil level is great
I do get white smaoke when cranking. Truck sat for 3 years so I am using 5 gallon can with diesel with a temporary fuel line hooked straight to pump under the driver door. Have notmhad a chance to drop and clean the tank yet. The truck started for about 30sec. first turn over. It ran rough which I expected but I cannot get it to start back up.

Welcome to the Forum 
Are you using OEM Sensors? They trucks don’t like aftermarket sensors or glow plugs. Keep the charger on your batteries during attempts to start your truck. Leonard has you pointed in the right direction.

I am using OEM sensors and they were expensive. I'm not sure if the gp are OEM. They came with he truck. I am getting P0605 p0475 P1118. I bought the truck and I drove it for a year or so then 1 day it went into limp mode. I got it towed home and started to work on it. Eventually buying AE and was pretty sure it needed and Idm after replacing everything. I finally bought an Idm in January of this year and started to work on the truck again. Boom finally got injectors to buzz and we were are where we are now. It's getting frustrating to say the least. I dont think it's the pcm. Getting all the signal wts light etc. That makes me believe it's good. I did check the gpr this past weekend and it seems.to be working properly. I dont have a way to test fuel pressure but I'm getting a full bowl, white smoke, and the diesel is disappearing out of the can.

Is your fuel ball heater plugged in? If it is unplug it and double check your fuse. Do you know what your codes are for or do you need a link for those? Since it’s been a while, and you did get it to start hopefully it’s something simple like just air in the lines.

There is an easy method to check fuel pressure with some hose and an inexpensive 0-100 gauge. Hook the hose to the fuel bowl drain. If pressure regulator is bad fuel could just be going into the tank through the return line.
65% ipr is high. Pcm is asking for more pressure. You said 2600 psi so not sure what's going on. Maybe time for an hpop dead head test.

Fuel bowl heater is unplugged. I actually removed the heater but I left the plate in the bowl. Fuse is still good.
I'm extremely confused on how icp 2400/2600psi when cranking and icp DC starts at the normal 14.4% but when cranking is maxed out.

You will need an ipr blocking plug, a dead headed hpop hose and a hpop hose with adapter with 0-3000 psi guage to test the hpop. Riff raff has the Ipr blocking plug. I took an old set of hpop hoses to a local hyd shop and had them cut off one end and add jic fittings to cap one off and adapt the other to the guage.
70-80 degrees you should not need glow plugs so probably not your issue

If it still does not start, we'll assume ICP is good, and IPR is climbing because we're not getting fuel. As has been suggested, see if you can get a fuel pressure measurement.
Does the truck have a chip? P0605 might just be from the performance chip.
What does FIPW (AE) or FUELPW (FORScan) read when cranking? Should be at least 0.6ms if PCM/IDM are in sync.
What is your cranking RPM and cranking voltage?
