so i got all the injectors in today and cranked the motor over to get the crap out of the cylinders. i will get the glow plugs in tomorrow and another idm and the ipr out of my truck just in case. i may try some wd40 to see if it will pop off. im still not getting any oil pressure in the driver head when we cranked it over today. but does anyone have any ideas as to why i am getting pressure at the line but none when i put the line back to the head and hook the gauge to the head? any help would be muchly appreciated. i also didn't find any oil o rings that physically looked bad.

 

Are the injectors seated properly?
Is the oil just pissing out of one of the injectors?

 

they are sealed fine. i will do an air test tomorrow just to make sure but i put some lube on them before install and all went just fine. i had this problem before i tore the injectors out. and i am not getting any oil out of any injector on the driver side??? im going to bring my spare fuel pump over as well. i may put that in to. thank you for the help.

 

Did you do a buzz test?
I hate to ask stupid questions but....

 

I think you are just going to have to pressurize that drivers side head with air to find the leak. Or if you have a porta power you can use that to do a head pressure test with the correct adapters.I'm kinda stumped too, nothing to do but test and narrow it down.

 

i have not done a buzz test. i do not have anything to do one. my father in law has a buddy that owns a repair shop and were going to ask him if he has something to do one. i would also like to read ipr % as well. i plan on getting ae (everyone i know has a powerstroke and im the one always working on them) i just dont have the money at this moment.

i am going to do that today as well. funny thing is that last friday when i hooked the guage to the driver head i got 1000+ psi right off the bat, so i switched to the pass head were i maxed out at about 900 so i though my problem was a pass o ring. i just wanted to double check everything sat so i hooked the gauge up again and cant for the life of me get oil pressure in the rail. i get 1200 out of the line if i unhook it from the head (icp unplugged).

will the gauge not read if there is air in there, say the injectors are not firing so air is just trapped in there? but air should pressurize as well i would think and give me a reading no matter what. and it will not try to start either if the driver side head oil is plugged in and pass is capped. it will try to start off the pass side though. last friday it tryed starting off both sides just fine, when i got pressure from both heads.

 

Where are you located? Maybe some close can come give you a hand with AE.

 

i wana thank everyone for there help so far. i got my hands on a movate sp? made by snap on, and did an injector buzz test came back ok nothing wrong there. i did a koeo test got a p1280 icp was unpluged, and a boost code. i plugged everything back in i got 500 psi on the pass head with a ton of cranking and it was trying to start. so i plugged the driver head back up and have been cranking on it for a bit. batterys are charging now, i got 0 icp pressure and 65% ipr, i also put my ipr and cps in got around 150 rpm while cranking. i dont think all the air is out of the driver head so im not getting any oil pressure yet. i will report back in a bit any other tests i should do while i have this reader??? thank you all again

 

ok got a little some were got 2400 kpa (around 380 psi) to the icp the manual gauge on the pass head never moved though, we did have the driver hose plugged and was able to build 500 psi on the passenger side with the icp unplugged after allot of cranking.

I got some smoke out the tail pipe. but the battery's were really low 9.4 while cranking. it started getting really slow while cranking so were charging the battery's tonight and see what happens. also i did the air test on both sides and couldn't hear a leak any were besides around the air gun. you almost have to be hulk hogan to hold the air nozzle on there without it leaking a little.

im going to put an extra fuel pump on that i have tomorrow because that is the only thing i haven't been able to check fuel pressure. it does fill the fuel bowl but very slowly so i figure its worth a try. but i would think it would run, with a bad fuel pump i had mine go completely out on me and it ran like hell and was only able to get going around 10mph but it still ran. anyone have a fuel pump go out and it not run at all?

 

so i went over and worked on the truck tonight, i am maxing out at 380 psi with the ipr at 65% it would drop to 64%. so i capped off the pass line and cranked on and all the injectors on the driver side are opperating properly. so i switched and capped off the driver head and hooked the pass head back up and the batteries ran out. thurs day i will go over and make sure the injectors on the pass side are working (oil wise). if they are im going to put my ipr in once more just to make sure, but im kinda thinkin the hpop is done. will a bad hpop hit 3200psi with a gauge to one line and the other capped off? and not build pressure when its hooked up normal? anybody help me out on this one? also got pressure on both sides now i had air in the system.

 

Before going any further, I'd suggest you pull the IPR, clean it, and shake it - it should rattle. If it doesn't, there's an issue.

This is what happens when you get air in the oil rails when everything is working:

 

the first thing i did after checking the fuses and unplugging the icp was i dissembled the ipr and cleaned it. I will check again when i put mine in. i want to make absolutely sure its the hpop. the one on there is a re manufactured one so? as soon as i hit 380psi on the manual guage and icp i stop building pressure. if i block one head off i reach 500ish and it trys to pop off, but doesnt.

 

im going to go work on the truck tomorrow, and was wondering if the injectors (oiling) check out fine and i put my ipr in and still cant get the truck to build oil pressure is there any thing else i should be checking out? im fairly certain there is nothing else that would cause it not to create oil pressure besides the hpop? i assume the icp is correct being as the pressure that i get out of the computer is the same as the manual gauge.

 

Ok I really need some advice now I took the fuel bowl and hpop oil resivour off. But with my Ipr I still can't build more than 300-380psi each head will build 500 until it trys to start. I can build 3700 psi straight off the pump with one line capped and the gauge on the other... Anyone thing I could not have enough flow but can build enough pressure?

 

The reason why I took the resiviour and all off was to check the bolt. I am guessing the pumps bad is why I took that off.. any advise would be greatly appreciated..
