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.:o

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.
