Thank you for providing information on how to perform this test. I found this very useful.

Will a regular air compressor be sufficient for this test? Mine only builds up to 100 psi maybe 105.

Probably so. Costs nothing to try.

Glad this was brought up I am trying to figure out a no start with no ICP and I am leaning towards the HPOP being bad but this will be a good test before I spend the money for the new one.

You're not putting air into the hpop, but air in the hpop lines. Remove the VC's and disconnect hpop lines AT the HPOP. Introduce a few lbs of air into the line and watch for bubbles around the injectors

Just above the top lip of the VC's there are two ports, one port has the HPOP line attached, the other (placed symmetrically) has a plug.....remove said plug and apply air there.

You can leave the VCs on until you have one oil rail leak down. Once you have a leaker, you need to find the source - which usually involves looking under the VC.
