Your building 650 psi hpo so no air test will get that high and is pointless to use shop air at 120-150psi range

But looks like HPO issue to me

 

Blades35 any idea on where to start?

 

Pull the lid on the upper fuel filter housing, turn the key and see if it fills quickly.

 

Yes it does. Here is a question: if you have a bad injector could that cause a no start when hot?

 

If he builds 650 ICP ID say his LPO side is good

Let it cool to the point it will start

Post ICPV @ KOEO

THEN POST
ICP AT IDLE
IPR% at idle

Then post the following at 2500 RPM
ICP
IPR%

Read this thread below hope I pasted it right on my Mobil

Why was all the work done

Same problem or did it start having issue after work

 

Cheezit asked if the IPR SCREENS came out each time the IPR WAS PULLED

Did they I'm curious too

He has lots more experience then I

 

Will post pressure and % tomorrow. Screen did not come off IPR. When we bought the truck it was not running at all. After a very hard start (many battery charges) it started and ran well but belched white smoke. Tore it done did oil cooler and replace EGR upgraded to tube style. Also replaced IPR. (Screen was trashed on IPR and had metal fragments in it) also changed screen by oil cooler (kit). Got it back together no start. Did a pressure test found air blowing back into the oil filter changed HPOP. Stated well after purging air. Took it for a 100km test ran great at all speeds. Got home turned it off tried to start it and I got hot no start. Tore it down re-did stand pipes and dummy plugs as well as all o rings on injectors put it together. Still hot no start tore it down again to re-check work and all o rings. Tested for leaks. Put it back together still hot no start.

When you said screen did not come off IPR do you mean it came out with it?
If not there may be 2 in there.

 

ICp 5v

IPR at idle 25.39
ICP 4340kpa

At 2000rpm
IPR 38.20
ICP 6863 kpa



At idle

 

Pull the oil filter and see if it's wet,,, dripping actually. Do you remember if the old hpop had black or orange seals on both ends (I'm referring to the main shaft the gear is bolted to). I've got a late model hpop bad in right now. It's a reman one too. I've only seen two bad hpops. I kept the first one because it's the only one I've ever seen,, until the one I have in now. But the first one had to have been tuned and overreved because the bearing gave way and the main shaft was extremely crooked. The reman one I have in now is not visibly bad like the other one,, but it is bad. Pointless info

 

Screen still attached to IPR

 

You said 85% IPR while 650 icp?? Was that while doing a cold start??

 

Oh,, and the late model bad hpop I have in now has had a long crank while cold for a while. But no hot no start.
