no start, low oil pressure

[Nyberg]

hi i loose al power on highway, but truck started after that, but no power and could drive any wear,

i have ae no, and when i crank it only shows around 400psi oil pressue,,

ipr, icp sensor changed,

havbe taken apart to se lpop but it dosnt look damage,
will take apart hpop and see how it looks,

original gauge for oil pressure move upp after 30sec of crank,

takes 30sec to fill upp oil bowl when i crank,,

where can i look now ? why no oil pressure ?

going to check hpop now, then change oil, new filter and out everything back and try again ?

need some help here,

you have a leak somewhere, it shouldnt start at all if its the hpop far as I know, Get the system tested for leaks with compressed air. Will give you a better idea as to where and what is leaking

[Nyberg]

do u have a guide how to check system for leaks ?

i dont see any oil around engine ?

You need to put Air to the ICP sensor port and listen. Best to get a shop to do it. Will your truck start after you let it sit for a while and let your oil get cold, say overnight? It could be a number of things. If the truck will start next day chances are its either leaking through your oil rails or standpipes or injector o-rings. All under the valve covers.

no it dosnt start anymore :/

we building it togheter now to test this,, get back when i know more,

does your dummy oil guage come up to normal during a long crank? If not you don't have sufficient low pressure oil to kick in your HPOP so make sure thats good first before you tear into things

my org oil gauge goes up to middle after 30 sec of crank,
and thats how long it takes to fill upp oil filter bowl,

is it on low pressure side i have problem then ?

[Deagle44]

its possible, shouldn't take 30 seconds for your oil pressure guage to come up, should be more like 5-10 tops. but its hard to say. Your best bet is to get it air tested for leaks first so as to avoid screwing around with it for ever. Generally with MOST high pressure leaks you can start it when its cool with the exception of an ICP sensor, HPOP and STC fitting, far as I know anyways!

i have filled up oil now and tried oil pressure on icp is around 430 psi
i unplugged icp sensor then it show 1380psi shouldnt it start then ?

fault codes i get is
egr but its unplugged,
P2614 CMP signal
P2617 CKP signal

we opend up hpop and changes some seals,, but when we open it up it startet to come out more oil from oil plug,,
Then its pressure there so i shouldnt have any leaks i think ??
but will make plug so i can try it whit air and see,

any more way i can check or od ?
i have AE tool connected anything i should try whit that `?

thanks for helping

have you changed your ICP sensor? 430 is low it needs min of 500 but 1380 when you unplug is LOTS! MIGHT I stress the MIGHT just be an ICP sensor. You can try swapping that out but might want to wait for some of the experts on here to chime in. I'm not real familiar with ICP problems only the basics of the system.
