1) 24 DME: Main Relay
2) 1B DME: Activation, Idle-Speed control valve/closing coil.
3) 7C DME: Activation, Solenoid valve, Intake Manifold (DISA).
(BTW: Replaced the DISA valve last year when I did the Intake gaskets, coolant and heater hoses. Replaced the Alt couple weeks ago.)
So what is weird, is the Fuel Pump runs and pressure is 50lbs when key is turned. Removed Main Relay, no FP, so I am guessing the Main Relay is good.
I just thought I'd ask in the event someone has an idea before I pick this back up tomorrow evening.

How long did you run the car after you started it? If you ran the engine for less than 3 minutes, you could have flooded the engine. When an engine is first started it is in open loop and the map for open loop is to provide a rich mixture until it goes into close loop. The amount of rich mixture is dependent on the ECT. The colder the engine the richer the mixture.
As for the fix, push the accelerator all the way to the floor and hold it in that positiion. This will place the engine in clear flood mode. Now crank the engine and see if it starts.
