Help I took the fuel pump out and can’t get the push rod To move

[IT Cowboy]

I have fuel squirting out the wee poles on my fuel pump. I took the old one off and now the shaft seems to be stuck at the bottom and I can’t get it to move. I’ve tried bumping the engine with no luck. There’s a square bolt directly below where the pump goes. Can I take that out and is that a direct access hole or are there any ideas how to grab that pushrod also does the push ride set on top of the pump rod or below the rod on the pump?

EDIT:

Ok, sorta disregard as I figured it out. I was looking for a push lobe inside the block and it is a push rod. I removed the square head bolt under the pump and the push rod fell out. The SOB issue I am facing is getting in there to put the pump in and get the rod on top of the pump plunger and then pushing it all in enough to bolt on. It is a ***** becuse I have AC and the compressor makes it all tight and hard to reach from top or bottom. I think I am going to have to have a buddy over to bolt it on while I hold it. Unless there is a truck to holding the plunger down while installing it

This is a minor thing and ppl replace these all the time but I remember changing the pump on my Ford in HS and it taking ten minutes. This is also tempting reason to go to the Sniper system and block off the mechanical pump. Oh and the hard fuel line connection doesn't line up with the pump inlet.

Thank you for the replies and help.
