Is the IPR OEM? How much oil is on the stick? It should never take this long to purge air... something is up. Cody test to see if the problem is in the heads or elsewhere.

This video is after a cup job - the rails were as empty as empty gets.

 

As jhl3 stated...try the old IPR first.

 

Yes, the IPR was OEM and brand new from the wrapper, but i can swap with my old one....i have a few extra ones.

 

also keep in mind I'm facing a bone dry HPOP, HPOP Lines, and HPOP Rails.

I'm just trying to determine the point at which i abandoned ship and look for bigger issues. Pulling the ICP sensor first, then swapping ipr's and then the Cody test seem like the limits of this.

 

Well no wonder you're having problems.

Fill the HPOP reservoir and the oil rails on both sides. Use the ICP plug on one side, and one of the plugs in the rail on the other side (front or middle).

Mine caught after 15 seconds of cranking.

 

well, that was the condition i started with.

HPOP res was filled, and I have oil on the rails (I pulled the icp and checked)

But this is why i think i have a High Pressure Oil side issue...but I've never had to purge the whole system before.

 

Can you check the HPOP reservoir again?

If you filled it initially, it should stay filled. If not....

ICP- two different things there. The one is the recommendation to remove and inspect for oil presence. I've not done that, probably messy (psi). The second is unplugging it to use the internal values of projected/expected ICP from the tables inside the computer.

What injectors did you put in? Are they stock?

Is there fuel in your bowl?

What is your CRANKING voltage at the batteries? Too low and you can crank all day without firing.

Is your UVCH plugged in? Some leave them unplugged until oil and fuel is pushed out of the cylinders after an injector job. Some others forget to plug it back in

 

Checked the HPOP fill last night and it was still good. I have pressure on the guage in the cab

The injectors are remanufactured Swamps Stage 1.5', these were purchased new from DP-Tuner

I have a modified fuel system but I have 55psi at the heads

I have a charger on the batteries will cranking, and they were charged before

I'm about 99% the UVCH is plugged in...my injector buzz test sounds good.

BTW, thanks for all the help so far everyone.

 

There was a member not too long ago that had replaced his HPOP. All went well until the truck would not start. Turned out that even though he thought the gears meshed well between the LPOP and the HPOP, they did not. The base of the HPOP was about 1/8 out from where it designed to be, this did not create a leak or any other signs of malfunction until the truck would not start. He did not see this gap/space until in a last ditch effort he removed the fuel bowl and then it was obvious.

I will see if I can find the picture.

 

Someone who knows more than I will likely talk about the injectors, if they need anything special.

Be sure to MEASURE your cranking voltage. It will sneak up on you. A little slow cranking but won't start. Keep cranking and it gets worse as the batteries drain.

Not trying to be pushy, but we can't rule out a factor until we measure and know for certain

It's okay initially to go with the odds, but failing there, we have to get into more specifics

 

Found it!

will double check that. i have a fuel bowl delete so it should be pretty easy for me to check.

I'll also double check voltage

 

also, what is the likelihood that one of the injector o-rings got fouled during installation? I lightly lubed them before install.

I feel like that would be pretty low....but that's all i can think of right now.

 

How about some pics while you're at it? Worth a thousand words as they say

 

Could happen, but it would at least TRY to start. Should start on 4 or 5 cylinders or at least get close.

Is it stumbling like it is trying to start, or just cranking?
