HG emergency

So I just tried cranking my 05 6.0 up after studs and cooler, ive cranked for a combined total of 3 minutes or so. ICP is reading about 2 psi during cranking. Im worried I damaged the branch tube or something. I tried unplugging icp still nothing.

Whats the normal time it takes to crank up after hg?
Should I see icp rise at all?
How much cranking does it take to start?
Whats duration and frequency of cranking is best to not damage starter?

Thanks

Everytime I have started a 6.0 after head removal I have started with a battery charger hooked up. I crank for approx 20 sec. After doing this 2-3 times I usually see baseline oil pressure. After that it always starts on the next crank. I usually give it a minute or so in between try's.

Does the oil pressure gauge on the dash come up?

Yes. Make sure to check your oil after cranking a few times. It could be low if you changed your oil cooler.

I poured oil in where the filter standipe goes to fill the cooler. Ill check the levels. As far as the gauge on the dash, ive never seen oil pressure until its started, never when cranking. Im at a drs appt now but ill keep trying when I get home. I was able to get an icp of about 16psi. Sometimes ill crank it and it will stay the same. Sometimes I crank it and it goes up a few psi.

Ok, oil level is good, the filter area is filling. Now icp wont go above 9.5 psi. Im going to keep trying every so often and if it doesnt start by thursday im towing it to a dealer to trade in.

Did you put the dummies in the correct hole? Usually the problem is in the injector hold downs, the oil rail and wiring/connection issues. 9.5psi means nothing if the IPR isn't closing, or it is commanded closed but remains open.

Fantom you just made my day with that. The reality is that ive spent alot on this truck and have only owned for less than a year. But I owe too much on it to trade in, so its cheaper to just get it fixed at the dealership than to pay the difference on my loan. Ill check the pigtail for the ipr tomorrow night. After that its off to the dealership to get fixed. Ive got way to many other things going on to be down a vehicle and trying to figure out what it is. If im not mistaken , the ipr plug should have + and - 12v correct?

9.5 psi means it isn't going to start. ICP psi needs to be up around 450 to start IIRC.
