My names johnny I'm also lusenuts on here can't seem to log in anymore.

Here's what is going on. I have worked on a lot of hear trucks and this is deft a first. Bismic or anyone else with more knoloege then me please chime in. XD

2006 Ford 6.0

Customer came in and had the infamous "HOT NO START" customer said he's owned it since new and never had any issues. [i also don't think he is very informed in maintenance] the truck has 103k miles I asked for some background on the truck to see if his STC had been replaced and he said he hasn't had any repairs done on the truck. So I went in and air tested the system and found a leak at the STC fitting it wasn't fully blown out but it was not clipped into place either. I checked the hpop pressure befor starting any work. I had 289psi icp reading. After finding the STC fitting and replacing the o-ring to the branch tube that was also very worn I thought I must have been spot on. Customer picked up the vehicle and the. Ext day started having the same issue. I checked it and didn't hear any leaks ended up pulling everything apart again and installed a new ipr pump and found a dummy plug bottom o ring blown out. Put it back together and I have 0icp pressure I checked the icp port and have 0 oil coming out of the hole.

These are the test and data I have done/come up with.

While cold
?ICP pressure 0.0 volts
?ICP .25-.26 volts cranking or not
?IPR 85 cranking 15 KOEO
?FICM sync YES
?FICM voltage 49.5 out
?FICM in 12.35 volts in
?LPOP 65 psi
?LPOP fills bowl in 5-6 seconds
?Ford filter and cap
?Cranking RPM 220
?Unplugged icp no difference (only matches desd psi)
?Tried a vacuum procedure on priming the HPOP nothing comes out of the icp hole

I know it can take some time to purge the air but I've cranked for a collective 65 mins. And never produced even 10psi of HPOP pressure and never had oil Coke out of the icp hole.

I'm beginning to lose it over here lol 5 times apart no obvious issues that I can see I would expect a bad pump to at least produce 10psi or at least have some oil dribble out of the icp port.

Thanks in advance

Update I removed the ipr again and put my ipr tester in put shop air into the system to check that the icon shows pressure and that the system holds pressure. I took it up to 151.2psi and it's been sitting for 15 mins and has dropped to 133.1psi I don't think I have any leaks I'm just not getting oil to the pump or the pump isn't creating any pressure. My assumption would be that the bearings and the pump it self isn't leaking. Just a recap I have 65psi lpop pressure and bowl fills in 5-6 seconds.

Another update I removed the oil cooler and found the sump is full of motor oil. The pick up screen was torn in 2 areas nearest the hpop suction hole. I assume that I must have gotten the one and only bad pump that Ford has sold in over 12 months. New pump going in today should be running in 4 hours.

Sorry to say no one had helped lol hope that I listed in the correct location.

I removed the pump and found that I left a red plug in the suction side of the pump. Hope I build pressure as soon as this is put back together.

Low and behold I go to start t and the starter gave out after all the cranking. I have 12v to the starter no engagement or spinning. So I'm installing a new starter. Then I'll let everyone know if it fires up.
