I second the suggestion to find some kind of therapist - anything really. Even just some soft tissue work on your paraspinal muscles (+glutes, hams) might help "wake" things up. And I don't mean in a not-firing sense - I mean it might help you get a feel for the muscles and help with proprioception.
In the meantime, I'd suggest for now stay away from squats, deads for the time being. Follow the squat rx video that a couple of us already linked. Work from the bottom up. Hold onto something so strength/endurance isn't an issue. Forget the back for a moment and squat down as far as you can. While down there, play around with finding & feeling lumbar & thoracic extension. Move your hips around, try to feel hip flexion and extension and what that does to your lumbar and hams. Do that a few times every day. I'd do the supermans daily too.
