Absolutely the most informative video for my international I've watched without all of the crap about themselves and their family!! Thank you very much!!!! Awesome video!!
I must say I believe I have watched every video on UA-cam. But this video was clear on how to set up and the results was greatly seen on video . Great job sir.
Great video. You gave us a lot of information and got right to the point. Other UA-camrs should follow your example and get right to the meat of the instructions. Thanks man.
Absolutely agree with you ! I’m still new to the You-tube video game but making clear and concise videos is paramount above all else ! Thanks for the comments I really appreciate it !
Great teathing video guys !! I'm have a no start with my 2002 dt466 bus. No oil pressure while cranking, now I know what and how to check it . Thank you so much.
I have an old f250 with a 7.3 I’m no mechanic but I’m listening and you are pointing to the ipr and saying that you changed the solenoid. The only problem is you are calling it the IPC. The ipc looks completely different than the ipr and one of the problems is getting oil in the pig tail again I’m not a mechanic. I’m grateful for all and any help I can get especially you tube videos because the folks making them are helping so many people. They wouldn’t be doing it unless they were passionate about the work. So thank you for making this video.
Yes Sir! I have been corrected a few times on this fact. It is the IPR (Injection Pressure Regulator) solenoid. I call it the IPC (Injection Pressure Control) solenoid in this video. I have ordered this part many times from different dealers/parts warehouses and the parts guys have called it by either name. I just chose to call it that here in this video. As long as the viewers understand what I'm talking about as far as the solenoid itself that is what matters to me. Thanks for the comment at this point ill try and edit it to read IPR in a caption. Not sure what pigtail your taking about, The IPR solenoid coil is a separate coil that wraps around the valve and housing itself. There should be no way of oil getting into that pigtail from the IPR valve itself for that reason. It would have to be getting oil in it from some other source externally.
@@peetky8645I'm sorry, but that's false. Oil in the connector doesn't cause the connector to fail. There are connectors under the valve cover for every injector that are constantly bathed in oil and they last a long, long time. Oil in the ICP sensor connector indicates a leak in the sensor. It doesn't necessarily mean the sensor is bad or reading incorrectly, but it would be a good idea to the change the ICP sensor fairly soon.
Dude thank you so much! You just taught me more about the problem I'm having. I replaced the IPC sensor and it ran like new for one day and just like with yours the next day it was back to normal starving for fuel. I was going to next replace the IPC regulator but now I'm going to find some way to get air into that hose and find out if it's an o-ring on the injector. You're awesome I appreciate your help
Thank You Sir ! Appreciate the Comments ! I figured it was a video that needed to be made. Those injectors were changed out by another shop two years prior so installation Issues I’m sure was the problem there.
Ive been working on a crank no start on my truck for a month. Im happy to go try this today after redoing the entire fuel system. It makes sense now that id be getting fuel but if the icp isnt getting enough high pressure oil no start. Thank you!
@@marshallsanders5672 It was a great video , I loved seeing that motor, so different if appearance but so similar in function, thanks again for the video
Thank you!! Will definitely give this a try. At first the scanner was telling me 200psi compared to the 725desired, but then it caught up and gave me the 700+ psi. Still no start without starter fluid.
The main issue with the hui injector is the gap on the top metal snap ring that doesn't support rubber oring right finally someone has come out with spiral metal snapping for top as well as Teflon cushion to support top oring
Very interesting feedback ! There was a glitch with the cameraman on the first take so we had to redo a bunch of clips. It all worked out ! Thanks again for the comments. Much appreciated
Both ways meaning after I tested both dead head at the pump and when it was connected to the engine. Still does not start. I disconnected the ICP and no different. Changed the IPR valve with no difference.
Ok gotcha that makes sense. Well not the high pressure oil system. Might not be getting low pressure fuel 50-60 psi from the mechanical pump on the side of the high pressure pump. Or injectors aren’t firing by the computer. Check for codes could be a cam sensor related problem computer not seeing RPM
Awesome video. I have a smooth start. Smooth idle. Untill I give it some gas. It stars rough idling, sometimes it’ll smooth out on its own. Other times I need to give it throttle and slowly release for it to smooth out. It did it after fuel filter replace. Possible air in system?
Yes definitely possible but should work itself out. Make sure the filters are tight enough, possible air is being introduced as it’s running. Could have introduced dirt into the system with the filter change. If nothing found may have to do a low pressure fuel test at the port on the filter housing. Just have to work that problem til you find the cause ! Thanks for the Comment! Much Appreciated
@MarshallSanders not sure how similar the electronics is from a dt466 and 6.0l Ford diesel but on a 6.0 if u unplug the icp the emc defaults to a pressure that allows it to fire the injectors without the proper high pressure oil pressure a limb home device built in on the 6.0 and may those engines
Very good explanation on what components and how this system works. What would be your advise to me having same issues on a scanner but engine hydrolocked?
Did you have an injector out already ? If so oil /fuel probably leaked down in that particular cylinder when you pulled the injector. A diesel has a very small Quench area because of its high compression nature and it doesn’t take much to hydro lock them. I should have mentioned clearing the cylinder before installing the injector back in the head but I did not.
Hey grate video, I have a similar engine the DT530 it's a genset and wont start, I have removed the high pressure oil sender and plugged a gauge in to see, when cranking it reaches 500 psi but no start, I have heard you need 700 psi to start so I'm going to replace the regulator solenoid and see if that helps. I don't have a scan tool, I think my orings must be okay but that was a good idea to pressurise the system with air to check for leaks, I think it also might me the ECM could have died and not firing the injectors??
Yep all the above ! I think at 500-600 it should at least sound like it wants to start if that makes sense ! Your on the right track though ! Let me know how it turns out !
Did you reseal all injectors and rail seals,change icp sensor , would change crank sensor too if original while engine cover is off? Thanks for video also, I'm learning everyday I work on bunch of old internationals with weird intermittent problems
Well that's a bit of a loaded question! These tests will work on any HEUI injection system... H (hydraulic)high pressure oil.... E (Electronic)computer fired... U (unit) all in one.... I (injection) system if that makes sense. Not sure what your working on but any HEUI injection system works very similar to what I explained in this video!!!
great video, I have 2007 international 4300 long cranking and rough idle when start cold, after it warm up for 15 minute, it will be fine. Is that oil leak from the injector o ring will cause that?
It is possible ! It’s all about how fast it builds the 500-700 psi to start. Possible drainback in your Reservoir. Wouldn’t hurt to check the low pressure fuel side also 50-60 psi on that.
Great video. I have a 2013 International workforce 46DT engine. I have changed the ICP, EPR. Now it's building more pressure with no leaks in the system from rail to injectors. The only problem is I have a leak from pump to engine, is this normal? Meaning it's not maintaining pressure in the hose/gage itself. Hope you can answer this or help me out. Thanks
Yes from all the trucks I’ve checked when you shut the engine down the pressure will drop. Usually it will have some residual pressure say 50 psi but eventually after a few minutes it drops to virtually 0 psi.
Thanks for your response. I'm having problems with it starting up. My gage it's going up to 1000 psi when cranking engine and drops pressure right away without any residual pressure. I have blown air into the high-pressure pump going in the direction of the engine and can hear the air bubbling the oil in it. My dought is if it could be any check valve in to the high-pressure pump or gear shaft seal not holding enough pressure?
It would seem to me that even if there is excessive leakage when you shut it down it should still start fine if it’s building to 1000 psi when cranking as far as the high pressure oil system goes!
I have a no start problem after replacing all 6 injectors. I open the oil temp sensor and had no oil in it. My truck is in a incline front high could. Could the incline be the problem of my no start?
I would fill up the resovior, don’t crank the engine. See if the oil leaks out after sitting for an hour or so. If it leaks out there is probably blown cover half gasket. If it doesn’t leak out then it must not be feeding the resovior from engine oil system.
@@marshallsanders5672 I poured the oil in the reservoir. check after an hour and it looked like it is holding the oil. I tried starting it and it took a while to started but I could see the oil pressure was building. It started and I let it idle for about 30 minutes then took it for a spin. It drove great. I am going to let it sit for a day and see what happens. I want to thank you for all your help @Marshall Sander great channel by the way and your step by steps are on point. Keep doing what your doing. Thanks again!!
Awesome ! The whole point of the video ! To get trucks like yours BACK on the road ! It sounds like it just lost its prime and cranking it wasn’t enough to get the SYSTEM up and running ! Keep everyone updated on how it turns out ! good Stuff!
I have a 98 International 7.6, I took off the fuel tank and washed it with water well. I connected the fuel hoses by mistake and gave it air pressure, then I corrected the error. I tried to start the truck. It never started. Can you explain to me the reason?
Not sure what you mean connected the fuel hoses by mistake. With water in the tank you gave it air pressure ? With no fuel in the tank and and gave it air pressure to”Prime” the system and now the system is full of air ? I just need clarification as to what you mean by connected fuel lines by mistake and gave it air pressure
I have a 466 also and can’t get it started. Did the pressure tests you just did and only have 790psi both ways. What would you suggest be my next step? Thanks in advance.
790 psi. Both ways? not sure what you mean. It had low pressure when it wouldn't start 240psi. After I fixed the O-Ring it built up to 790 and started.
Good day Sir, I have the problem for my Engine T444e only Timing cover Of Engine will remove then after Fix the Engine not Start Only Cranking me I know what is the Problem of this.. Thank Sir
Hi Marshall I hooked up a fuel pressure gauge it reads 45 psi I hooked up a oil pressure gauge it went to 1200 psi I changed the icp switch in the oil rail it was leaking and the ipr I changed for preventive. it would only start with starting fluid ant I'm trying to get it to start on its own
@@marshallsanders5672 Thanks for getting back to me . I found the injector harness disconnected from where I removed the ecm mounting bracket. It will only start with starting fluid when cold
Absolutely the most informative video for my international I've watched without all of the crap about themselves and their family!! Thank you very much!!!! Awesome video!!

What happened
makes me want to go back to all mechanical from the 70's..😅
Sure does!
Thanks for explaining the injector system. I never realized it used oil pressure form the engine.
Your welcome glad you have a better understanding now !
Great review of how to troubleshoot HEUI injection system.
Thank You, Appreciate the Comments !
👍🏻 Nice find. We don’t come across too many leaking injectors for that year model 466 in our shop. Enjoyed your video.
Thank You Sir ! Appreciate the Comments ! I figured it was a video that needed to be made. Those injectors were changed out by another shop two years prior so installation Issues I’m sure was the problem there.

Yes Sir ! Low Pressure Fuel 50-60 psi and must get 600 or so PSI Oil From the high pressure pump just to start.
Thank you for your experience and sharing your thought process. Very helpful
Very interesting to see that kind of 7.3, great job
It’s not a 7.3L ford , it’s just the 7.3 L works identical so it was worthy noting in the description
@@marshallsanders5672 It was a great video , I loved seeing that motor, so different if appearance but so similar in function, thanks again for the video

That’s what mines is doing but starter fluid stop working to start it

Solid gold .
Thanks appreciate the feedback !
The first thing you changed was the IPR the ICP was not addressed!
Yep I stand corrected I've gotten some flack for that one, I just misspoke the part name. Thanks for the comment
Great content! Thanks
Thank You appreciate the comment !
Great video thanks!!!!
Thank You glad you got something from it !
I got to give respect to the camera man also. Trust me I watched many videos on these systems.

Hello
Good teaching in your video.
What T fitting did you use? Or fittings that was presented. Thanks in advance.
#6 JIC T-Fitting, #6 to #6 JIC strait fitting, And pipe plug to #6 JIC to adapt it to the gauges.
Great video! What scanner do you have?
The one I was using is an AUTEL Medium/Heavy Duty MS908CV
You didn't show how to replace the pump
The pump wasn’t the problem, I will show that when one comes in the shop needing one replaced!
Hi Marshall
I hooked up a fuel pressure gauge it reads 45 psi
I hooked up a oil pressure gauge it went to 1200 psi
I changed the icp switch in the oil rail it was leaking and the ipr I changed for preventive.
it would only start with starting fluid ant I'm trying to get it to start on its own
It would seem at this point the injectors are not being triggered by the computer.
@@marshallsanders5672 Thanks for getting back to me . I found the injector harness disconnected from where I removed the ecm mounting bracket. It will only start with starting fluid when cold
Does it start hot on its own ?
Ipr is what you mean. Not ipc.
Yep I've heard it called all the above before ! Thanks Injection Pressure Regulator/ Injection Pressure Control Solenoid
I'm looking for some help
