2004 C32 will not crank.

2004 C32 AMG, 81,XXX miles, completely stock (no mods).
The wife and i went for ride, about 25 or 30 miles into our ride i felt a little hesitation, it only lasted about a second. No CEL or any other warnings appeared so we kept riding for another few miles. Stopped at a convenience store to get a couple of drinks, (when we stopped, everything was normal, no warnings of any kind) when i went to start the car, the engine would not turn over. Checked all the fuses in the car, no blown fuses.
when i turn the key, everything is normal, i can hear the fuel pump come on but it will not crank. Took the starter relay out, and used a jumper to crank the engine, engine cranks over and sounds normal, but will not start and run.
Transmission shifter will not come out of "P", imagine my troubles trying to get it on a tow dolly with the car in "park" at 3:30AM
(steering wheel lock, disengages normally with the key)Only 2 issues with this car since i have owned it, about 4 years now.
Replaced the battery about 2 years ago, and the alternator about 6 months ago.
Can i get some suggestions please?

Thanks.

Scanned it, no present or stored codes.

I have scanned this car 5 or 6 times, there are no codes present or stored.
Brakelights work when i push on the pedal.
Everything else works fine (stereo, command, wipers, headlights etc etc) when i try to crank it with the key, nothing happens.
If i remove the starter relay and jump the 2 terminals on the relay block, the engine cranks, but it will not start and run.

The R230 (SL55 in my case) has a plastic lever that breaks and prevents shifting from Park, but I believe the car is able to start. It is a beotch to remove the shift housing and tear apart, but I've done it.
Investigate and see what you can find. Let us know the fix.
If you can hear the whirl of a pump going when attempting to start the car you may only be hearing the primer pump.
It is a long shot, but given your situation it may be worth it to quickly check if you have pressure at the fuel rail when trying to start.
Unfortunately the fact that you have to bypass the starter and even then it won't crank, probably means something is telling the ecu to not let the engine start.

This was posted by another member here (forgot to get his name, all credit goes to him) In the cupholder area, using a flat blade screw driver, pry up the coin holder, you will see a round hole in there.
Insert the flat blade screw driver in the hole, and push the little black tab straight towards the front of the car. Now your shifter is unlocked.
Ran the shifter through all the gears, while holding the key in the crank position, still will not crank.

Ignition switch?
Many have had success by replacing the cam or crank sensor on the engine.

When i turn the key to the 3rd position (crank) my engine does not crank, (does not turn, doesnt do anything) bypassing the starter relay gets the engine turning or cranking. fuel pressure seems OK at schraeder valve. Will check for spark.
Hopefully i will get to it Saturday.
Thanks.
