so what do you get for ICP and IPR% at hot idel on Scan Gauge this will determine the HPO system condition
thats to bad the mechanic was changing parts and Praying one would fix
and what year is the truck

It's a the 2003 6.0 with 127000. He said that with the 4 new injectors in im at around 700 or 800 psi and it still won't start. He said it would crank just not start. I just got off the phone with him and he said they gotta take the cab off and check the pop and something else with seals. And I dont know what the readings were with the scan gauge I got it after the truck broke down. So what does it sound like he is doing?

To me it sounds like he doesnt have a clue in hell
with 700-800 PSI ICP thats plenty of HPO pressure to start and the HPO system is not the Issue
you only need 500 psi to start mine Idels at 640 HPO psi and you definattly have that
I think he is ripping you off dont let him pull the cab get it out of there

I just got off the phone with him. I told him it sounds like the 4 new injectors weren't the problem so I wasn't gonna pay for em. Also he said he is gonna check the hpop and the piping around it and o rings. I ain't gonna pay 1000 bucks or more for crap I don't need. I'm gonna let him check it another day or 2 and go from there and I def ain't paying for crap I don't need and he knows that's now.

Also, I posted this (below) on one of your other threads. Didn't get a response on it:
Did you try starting it w/ the belt loosened/off as suggested?
Am I correct in saying the mechanic stated the following:
1. It is the ICP
2. It is a high pressure oil pump issue
3. An injector is leaking (high pressure oil I am assuming)?
Unless he saw low ICP readings from the start, it sounds like he is guessing. Without codes and diagnostic information, that is all we would be doing.
Ask him what the ICP reading and the corresponding IPR duty cycle reading are at KOEO and also when cranking. Knowing the specific code numbers would help also.
With all that cranking, make sure your batteries get fully recharged ater giving them a work-out. In fact, I would have charged and load tested the batteries as the #1 task at the very start. I would also want to know the FICM voltage at KOEO and when cranking. Even if you have an issue in the high pressure oil system, you need to confirm good FICM readings, IMO anyway.

Per post above:
Ask him what the ICP reading and the corresponding IPR duty cycle reading are at KOEO and also when cranking. Same w/ FICM voltage.
As others have said, 500 psig is all that is needed to start. Mine doesn't get to 700 psig.
I would be quite disappointed about a diagnoosis of a leak on one side that led to 4 injectors ...... and still a "no start".

i am by no means as intelligent on these motors as blade and bismic.... they are amazing at diagnosing problems over the computer. but i have been having a problem with my truck resulting in many hours on this forum and i have read and reread the entire tech folder.... apparantly the FICM causes a crank and no start scenario so i would do as bismic is saying and have that checked... its all in the tech folder ... print it out and give it to the mechanic.... and if the cabs off have studs put in... just a thought... i would... but good luck to you... i hope it all works out

bismic i am pretty upset, im a college kid and dont have lots of money. especially to pay for things that arent needed. i think he is trying but just not finding it. i dont agree with the 4 injectors and i told him that today and that he will put my old ones in if thats not the problem which it isnt cause its still not working. and LSAtexan4x4 i will def look into that right now. im just really frustrated cause its been over a week and it doesnt seem like we have gotten anywhere except that the new injectors increased the psi by about 300. which from what i hear is normal cause they fire a little differently. just frustrated cause ive always wanted a diesel and i finally got one and i now know that the 2003 6.0 does have problems and thats ok just gotta fix em as it happens and ya never know this may be it, but i wouldnt get rid of that truck for nothing. thanks for all the help guys i really appreciate it.

Theres one thing that mechanic is not counting on is this FTE Forum that has a ton of info on here
He cant BS YOU as easy as some of his other Clients
To bad you didnt have that ScanGauge B4 you took it in
this is the first time Iv heard of someone wanting to remove the cab to check the HPOS
Mechanics like this really make me wonder do they NOT have a Clue
or Do they know exactly what it is but exaggerate the problem to Boost cost
and another thing is the 2003 has a pretty reliable HPOS they just dont have the Failure rate as say an 05+ does
Mark Wasnt Kidding when he said watch it be the FICM
was there any other recent work done an oil change anything
