From what I understand that shouldn't be enough to make that part your issue. But what you need to look at closely that I couldn't see in the pic is whether or not there are any small holes in the screen. Reason being, the HPOP can produce small slivers of metal that can go through the screen like spears. These make the smallest hole but are perfectly shaped to block the valve from closing. That said, yours doesn't look bad from what I can tell. My next effort if I were in your shoes would be to check the fuel pressure. Your fuel pump duty cycle is always 100% so that's not much help (unless you see it's not...). What you can do is pull the lid off the upper fuel filter housing, then turn the key on (DON'T CRANK IT). I was able to stand in my open door and see down into the filter housing and the housing filled with diesel in just a few seconds. Turn the key off before it spills over obviously. This will help you know you're pumping. The p0232 can be caused by power issues to the fuel pump. "The fuel pump secondary power circuit has a short to battery voltage" is an option that could cause you to not run. I'd focus here.
Also, I apologize for not telling you to check the fuel bowl (filter housing) filling before you dug your way to the IPR, but the crazy readings on its duty cycle gave me tunnel vision. I bet that valve would have to do some funky things if the fuel pump was providing only intermittent pressure. Again, good luck!
