I couldn't even get my hand in there to get the socket on the nut. I guess I'll just have to give it another go.

I just turn over the ignition and after 3 tries it as aligned...just by bumping and looking...what are the odds

It's a tight space but you do it as follows:

Put socket on 1/2" ratchet.

Shove socket into tight space, perpindicular to axis of engine. There is barely enough room for the width of a 1/2" ratchet.

Rotate socket 90° so it's now aligned with engine centerline.

Move socket and wrench rearward to engage nut. Wrench moves to the furthest aft point in the available space.

It's a PITA, but you get reasonably good at it after about 30 tries.

If you don't have the deep socket for the injectors, then you need the perfect length of extensions to get it right. I did this once, before the deep socket, but can't remember the proper length.
