I do not have access to AE. My truck does not start and I want to know if I am testing the HPOP correctly. I disconnected both oil lines from the pump at the heads, I plugged one line and on the other I set up a liquid filled gauge with a 2000 psi max rating. I cranked it and I am only getting 175 psi. The HPOP reservoir is aways full too. Before I did all of this I replaced the ipr with a new one from ford and a new HPOP gasket as well and the truck still did not start.

Sounds like you tested it correctly. Need 450-500 psi to fire.
Not sure I bought the truck not running. It might be the original pump. This truck has 76,000 miles

How do you test the LPOP? And if the HPOP reservoir always stays at the correct level shouldn't it be working properly?

Yes, sounds like you tested HPOP correctly by dead heading it.
You may want to look at sending the pump out to be built into a T500 if you can spare to have the truck down a few more days... https://www.dp-tuner.com/ford-power...l/high-pressure-oil-pump/terminator-t500.html
