I had the exact same problem at fusionchickenleg in my wife's 07 m35x. Lights come on, even radio and such, but would not turn over. did all the same things he did with no result. then found a video on youtube that identified the ESCL (Electronic Steering Column Lock) as the culprit. If this is the problem, you will see a yellow key signal on your dash. Tapped on the metal box on the steering column under the dash with a screwdriver handle while pushing the start button, and viola! Car starts right up.
That bugger locks and unlocks your steering column and communicates with the ilock system. For my wife's car, it didn't lock the steering wheel when it turned off, so next time around, it gave the ilock a "no go" signal and the engine won't fire. tapping allowed the mechanical portion of that actuator to move and give the ikey the proper signal.
based on what I saw in Nissan forums, I am going to experiment with cutting off the lock motor power feed once the car is in acc and unlocked. The steering will no longer lock, but it should still give the iKey the okay signal.
A proper fix for this requires the purchase of a $1200 part, and another 3-400 in labor, as the part is installed with break-away security bolts that have to be drilled out to remove. Infiniti will act like they have never heard of this problem, even though Nissan had to do a full TSB on a very similar problem with the 09 Altima which was leaving drivers stranded. https://www.youtube.com/watch?v=oOTh3PqYh20
