2006 Sonata Error Code P0346

My 2006 Sonota V6 3.3 suddenly paused & stopped accelerating. "Check engine" light blinking, "ESC Off" light on. Even when flooring it no acceleration nor rpm increase (this is "limp home mode"). Got error code P0346 (Bank A Camshaft Position Sensor) and a few other codes indicating cylinders 2 and 4 misfiring). Btw, Bank A is Bank 2 (crazy, right!), affects Cylinders 2, 4, & 6. There are 2 cam sensors on the V6 3.3. Bank A or 2 is located on the front right of engine closest to radiator. Fairly easy to access and replace ($60to$100). But after replacing and leaving battery disconnected for 2 hours, car still won't start and I don't know why (battery still has plenty of juice). Does anyone know the next step?
Guys, please help. I'm clearly not a mechanic. I only posted what I've learned so far to hopefully help someone along the way.

Forgot to mention reading "0 codes" but still won't fire up. Just 1 click then nothing. The battery is good.
Any ideas guys?

Bank 1 should be the side that has cylinder #1.
I don'to know if Bank 1 = Bank A, I don't have a FSM handy.
