She bucked and now wont start

O.k. rooster from the picture you supplied, by memory, if you look a the very edge where you show the rust colored bracket that holds the plastic cover, the port we checked was right behind it. Had to take the rust colored bracket off to get to it. No oil pressure on that fitting. I thought for sure that was the right one, but now that I see your picture it might not have beenb. Oh. well I guess I will have a new low pressure pump whether I needed it or not.

What port did I check?

That's the oil pressure sender for the gauge cluster, your right. The EOT sensor hole would read the same pressure if you tapped there. If you still don't have pressure where you checked with the new LPOP you aren't getting a supply to the LPOP.

With a good low pressure oil system you will have the same pressure there as the rod and main bearings in a no-start situation.
