Really confused, need help! temporary no start

Hey everyone, I could really use some help here as I dont have any confidence in my truck ATM (and its my Daily driver)

Here are the sequence of events (that I am aware of) leading up to the issue.

No issues at all since buying the truck. I did however do an EGR delete about a month after buying it, close to a year ago. I have not touched anything on the truck for a long time.. probably 8-10 months. I do regular 5k oil changes and 10k fuel filter changes.

So I drove about 25 miles and got gas. I left the ignition on (eng off) during fueling. This bonked my fuel gauge.

I then drove about a mile to a parking lot and during that 1 mile drive I went WOT (which I do occasionally) for about 10 seconds then coasted and went slow for about half a mile with the truck idling so as to let the turbo cool before shut down.

I came back to the truck about 1.7 hours later and NO START. I messed with it a bit, unplugged my batts, checked the emergency fuel shutoff switch and replugged the batts. This fixed my fuel guage, but still no start.

I was suspecting bad fuel so I drained the water trap and observed a light GREEN tinted fuel.... The kind people who stopped to help were convinced I put in gasoline. I am certain however I did not as a return trip to the gas station verified the green fuel came from the diesel fuel pump... On a whim we also went to another station and the same fuel color was observed. IMHO fuel issue eliminated.

When I returned to the truck, it started but not with any authority. it idled for about 30 seconds and then died not to be restarted again.

Towed home.

I did some research and set up my scan guage II to read ICP, IPR , FICM v and FICM Sync

Went out to truck (now cold) and it started but died shortly after. I watched the Scanguage and the FICM values were good ( so I will not reference them again)

After another attempted start i saw ~85% ICP and the IPR came up enough to start... however It again began to dies as the ICP fell off to 0.

So at this point I am thinking either the IPR or ICP sensor is bad. I came inside to read up but ended up going out to the truck because I wanted to write some hard numbers down first. I cranked it and it started up with authority! It continued to run so I let it get up to operating temp.

These are the numbers I recorded

@ cranking ICP reached 500 IPR 85%

@ idle ICP 640 IPR 23

@ 1500 RPM ICP 850 IPR 850

I was able to shut down and restart multiple times with no problems and the same numbers observed... This is disturbing to say the least!

What do you make of this and what should I do? Is this an IPR going bad or an IPS sensor?

I could just pull both and inspect them, but Id rather have some input before tearing into it.

Your time is greatly appreciated!

Since this was a random thing that seems to have fixed itself it would be only a guess at the cause. Nearly impossible with any degree of accuracy. It could have been anything.

Check the pigtails on the IPR and icp sensors. They are know to cause issues. Also, your last numbers says icp 850 IPR 850... Did you mean IPR 85%? If so, then you have a HPO leak somewhere.
