911 truck stalled wont start no hpop pressure
 

So I was driving to work everything was all hunky dory. Then it stalled, it would crank fine but wont catch so I check3d my ficm because I was vetting a p0611 with random Injector codes. But it tests flawless 48 volts the entire time. I was getting no smoke so that tells me its not glow plug related. So I figured hpo problem. I pulled my icp sensor and there was barely even a trickle coming out while cranking. I went and pulled the hpop and it looks fine. When I turn the wheel on the pump I can bear it suck and push. So to me that would say the pump is good. Ive been trying to find ways to check it but it seems like its working.

I pulled the oil cooler and noticed the screen on the filter was torn but I didnt see and debris in the channel.

The only thing I havnt checked is the standpipes and dummy plugs and oil rails.

Any help is some help.

Thanks guys
