Is the ECU right on the engine or mounted to the chassis? Thanks for bearing with me, this is my first hoe and still learning.
Looks like on the trucks it’s on the chassis, so it will not have cooler.

I'm waiting on the scanner. I flushed the coolant this summer and it hasn't used any since. It's an 09` so I believe it's computer controlled.
With that display you can not get codes through it . ECU does not have flash codes .You will need the tool .Is that a dash 5 you are working on ?
Let me know.

Hello Tool King! Do you have an opinion on TEXA off-road package?

I have not used that package . A friend of mine has it .He says he likes it . I can ask him what he likes and dislikes about .And let you know .I run Windr,JD MPDR,Pocket Fleet and many other sofware depending whit I am working on .

Dash 3 , dr zaxis comes in 4 more days. I pulled all the sensors and reinstalled looking for a bad connection but to no avail.

Can you ask your friend if he is able to communicate with anything beside Engine on JD CE?

Ok. Everything I see regarding this engine says it's common rail injection. You stated there may have been a fuel issue but never followed up with what you found. Just that you cleaned the tank and filters and flushed the lines. Did you find water? Was your separator in the circuit or bypassed? The reason I'm asking is rail systems will not tolerate any water intrusion. Isuzus have some of the highest rail pressure there is. I believe they actually pioneered the tech with GM . Anyhow, point is water is erosive under that kind of pressure. You will find ,if you take apart your high pressure fuel pump, erosion on face of pump plungers and barrels. Once that perfect surface is harmed, pressure rise becomes inconsistent. Pressure regulator valve also begins sticking.
I'm not saying this absolutely your problem, just that it could be. It depends on whether or not your engine ingested water.
Good luck.
Oh, if it had water, don't cheap out with one injector and this part or that. I know it's hard , but plan on a system replacement. The alternative is kicking the can down the road. It'll hurt worse down the road as you have good parts get hurt by bad . Been down that road, it's dark. Lol

I think he will explore every other option until there’s nothing left, i am (and I think others) afraid even to suggest something like this before other venues are checked out. Having rough idea about prices.

I get that, that's why I asked if he had in fact had water or debris contaminated fuel. I have tried in the past to save folks a nickel . Clean all, replace only what is out if range . Within a week or so, we are revisiting, chasing a moving target. In the end it winds up costing more with wasted labor , travel etc.

And I fully understand that, but you know that hope dies the last!

When you have time, please take a look. It's a good, lengthy read. It clearly explains what I try to say.

Good read! Especially about biological contamination, which most of the people overlook, and then: “it worked perfect when I parked it three years ago! Now I have to clean the whole fuel system”. I did dabble with stuff on marine side - so I know all about it, and about fuel polishing systems too!

BTW biological contamination affects not only fuel but hydraulics too!

G..G..G..Granville.........!! Fetch your cloth.
I first came across biological contamination maybe 15 years ago, but surprisingly it was not related to a single machine that had been parked for a long time but in a bulk fuel storage facility on an operating mine site that consumed in excess of 50,000 gallons of fuel per day. You can imagine the problem with algae plugging fuel filters on a fleet that big.....

Translating from the Spanish report I have from back then ...... "These micro-organisms live in water and feed on the hydrocarbons present in the fuel. They are often referred to as "humbugs". They form active and exponentially growing colonies that can rapidly disperse throughout a fuel storage system, resulting a rapid plugging of the recirculation filters (and filters on equipment) with a slimy deposit, most commonly a dark green colour but can also be brown or black. Draining water from the storage system on a regular basis can potentially reduce the microbial activity but will never completely eliminate it. The only form of eliminating the microbial activity once it has established itself in the storage system is by treatment using a biocide. The use of 2-micron (absolute) elements in the recirculating filter system of the fuel farm is also recommended to trap the micro-organisms in one place in order to clean out the storage tank. In extreme circumstances it may be necessary to drain a storage tank completely and treat the inside of the tank with directly-applied biocide by spraying."

I'm not a chemist but if the micro-organisms live in water and feed on hydrocarbons I can't see how they could be present in a hydraulic system unless it had significant water contamination in it.

I'm thinking all oils are hydrocarbons and one of the big problems with hydraulic oils is water retention .

Yes! Hydraulic oils do not emulsify easily so when equipment sits for a long time the water and oil start “layering” and that’s exactly where the bacteria starts to grow. It is especially pronounced in marine equipment where water cooler than the air and tanks “sweat” all the time. The fuel polishing systems is basically separate pump with several filters on the timer, it flushes fuel through filters from time to time using shore power.
