The car is stock.
The smoke started immediately (5 miles) after addition of fuel injector cleaner was added to the fuel system.
The smoke smells rich, and is like cold operation OL conditions (which it is). I'll throw the new HEGO sensors in there to let it go closed loop and see what happens.
Here is a video showing it:

1. Fuel rail pressure was instantly dropping to zero at key off
2. Engine was flooding to the point of hydrolock on start
3. MIL codes for low cranking fuel pressure
4. soiled plugs
5. rough idle/stall
6. copious acrid smoke from exhaust
After the tear down, I found standing fuel on the port side of the intake valves on Cylinder 2 and 5. (other cylinders were ridiculously coked up, but dry).
I replaced the fuel injectors on 2 and 5.
Example of coking on intake port of head (Typical for all ports)
