Can you prime the hpop through the plug in the top of the pump. I have an 06 with the newer style hpop.

 

Pre-fill the reservoir.

If inclined you could pre-fill the oil rails thru the ICP sensor port on the passenger side and the plug on the driver's side.

Pull FICM relay and crank engine until dash gauge registers oil pressure.

Re-install relay and crank. Usually after a couple 20 second spurts.

Yes you can but that is actually a test port. I usually just charge the batteries and crank for no more than 20 second intervals with a minute of cool down in between. Once running and up to TEMP, I go out on the highway and give it 5 hard accelerations WOT. All the air will be out of the system by then.

 

I've just been putting oil down the very center of the oil filter housing you will have to remove the oil filter standpipe to get the oil down the center of housing or hold the oil filter housing drain down while filling with oil

This cuts. My crank Time down considerably it will usually start within the first 20second crank

There's a couple other good ideas in the other posts to

These starters are tough you could crank for a minute solid and not cause any harm.

It's when guys still tring to start with issues/problems and they crank for hour or more with a battery charger hooked up giving little time to cool down they get desperate for it to start

Even with a dry system it should start within a couple minutes of cranking if it don't start after that much crank you have other problems to address

 

I give on this piece!!!!

 

Ok while trying to start this piece I removed port in top of HP Oil rails. Cranked until oil came out these holes. Installed plugs and put a mechanical pressure gauge in ICP port and was seeing about 200-250. I figured since IPR was open it would build when I hooked everything up and cranked from ignition switch. Pressure through mechanical gauge showed 75 at most.

So I went back to square 1. Applied air to ICP port, 100 psi the best I can do. I hear a little gurgle and air sounds like at the pump area. I hear air moving listening through oil filler cap. When I close IPR I hear that stop, I still hear small gurgle around pump area. Turbo is on so I really can't pinpoint exactly where around pump.

 

Is this a new pump or are you having issues with an old pump? Gurgling out the turbo drain back is more than likely a bad HPOP.

Here's what took out my HPOP. The tang broke off and was inhaled. New pump cured it and I had same symptoms except I'd only build 30psi if that.

 

This is not a new pump. I did new seals on standpipes and dummy plugs, upgraded oil cooler, and EGR delete. When everything back together my new problem no high pressure oil pressure! !!

I thought maybe a priming issue.

I have cranked and cranked, never builds any pressure.

 

I dont know how far you took it down but did you check the STC fitting on the pump? Was it ever updated? Did you replace or check IPR valve and/or screen?
To start, can you get some numbers while cranking, like IPR%, ICP psi?
