2005 Excursion 6.0 long crank cold
I've got a 05 excursion that has a long crank cold, icp is slow to build. This is especially hard to start after sitting overnight. Ficm voltage, icp and ipr seem to be working as they should. I have applied shop air at the icp and when closing the ipr I don not hear any hpo leaks. LPOP is registering on the dash. After it warms up it starts better but still a long crank. I am not sure what to check next. Any suggestions are greatly appreciated!

It's possible the oil rail is draining down overnight, likely the dummy plugs.
Here is a good vid from DTR for starters.
Since you have an Ex, it's possible your ICP is not on the passenger side valve cover, it's as easy as lifting the hood to verify.
If it's not, then it's under the turbo, which means you have an early build and could be the pump is getting weak.
If this is the case, park it nose down overnight and see how it starts the next morning.....that would tell us the pump shaft seal is going bad,
Excursions did not seem to always have rhyme or reason according to the year and what engine they had. I know of several posts that the owner had an 05 but an early build 03 or 04 engine.

Ok, the next thing to do is look at the valve cover sticker to see what model year the engine is, telling us what style HPOP you have.
Being it's an Ex, it might still have the cross over "hybrid" engine as I call it. It has the updated wavy oil rails, this we confirmed with the ICP on the valve cover, however it might still have the old style HPOP.

Good to know, you have that going for you then as they rarely fail and when they do "fail" it's often a case of a mechanic not knowing what else to look for. It's a very robust pump compared to the early build.
You can park it overnight and then pull the ICP sensor in the morning. You should see oil right there under the sensor in the oil rail, or not as shown in the video. If not then the odds are you have a dummy plug leaking down. Could be a stand pipe but as Ron mentioned they don't tend to fail like DP's do.
How long are you air testing it and what kind of pressure are you using for shop air?
Remember it takes 500 psi just to light the burners, how long of a long crank cold are you talking?

Ok it has the updated dummy plugs, tonight I pulled the drivers side valve cover and ran the truck for about 10-15 min and went and looked right below the icp and there was a stream of oil coming off the rail right above the #1 injector. I'm guessing it coming off the ball tube o rings?

That is possible but hard to confirm, injectors weep some and you might be seeing that. I would air test it, but if nothing else let it sit overnight and pull the ICP to see where the oil level is at. Might still have a bad one other side.
Technically that is #2 you were looking at, not that it matters unless you need to know specifically for some reason
Asked earlier what kind of shop air pressure and long of a test? Leaks can take some time to show up at times.

I would pull the IPR and air test from there. I found out the hard way that two top injector seals were blown causing a hot no start issue. It took 2 minutes at 180 psi for injectors #2 and #4 to show their colors.
From the sound of things you have a 2005 engine like I do. So I'd check your OASIS report and see if the STC fitting has been done on your truck. Mine would do this hot and cold and turns out the dummy plugs and stand pipes were never done on mine, just the STC fitting.
Ford or whomever, may have only done one side when it comes to the dummy plugs and stand pipes. On my buddy's 2007, they replaced one side and when they other blew not long after, they replaced it. Both sides should be done together, but some people just do one side because the passenger side looks challenging when it's really not.

I am using an adapter and hooking it up to the icp location and about 150 psi not leaving too long as I read it will burn up the ipr if voltage is applied longer that a min or so. I came home this afternoon and pulled the icp and the rail is full of oil. Also in my previous post I stated I pulled the driver side valve cover but it was actually the passenger.

Check the driver side and see what the seals look like on the dummy plug.

This is why I recommend people test from the IPR port to begin with.

I did a STC recently, air tested from the ICP and never really showed up.
Broke down and bought the IPR air test fitting, about a minute later the old classic hissing from you know where. This one was not like one I had where I pulled it apart with my fingers, but it was loose and leaking.

So today I put air to it again and could hear some coming from the hpop cover area. Since I did not know if this thing still had the STC fitting I decided to pull the cover. It has had the updated fitting installed. So I removed the pump, made a block of plate to mount at the branch tube, then applied air again and I have no leaks, left the air on there for hours. Is it possible the pump is bad? Thanks for the help

It's normal for some to blow past the shaft seal in an air test scenario, likely what you are hearing.
It's possible the pump is bad, unlikely but possible.
Are you seeing quite a bit from the injector top seals?
