The EDC pump control used in the OM606 turbo is not the same as the old purely mechanical pumps of the earlier engines.
I recall testing this on my OM606, it I pulled the fuse that fed power to the EDC control unit the car immediately quit and would not restart until the fuse was present.
Do you have another key? I'd try that.
Again I think you have some sort of drive authorization failure. You won't be able to bypass the stop solenoid or manually jump the K40 start relay without the proper start authorization process being completed.

Understood. Unfortunately I have just the one key.
The car sometimes does nothing in crank position yet other times it will crank for a second or two. Never long enough to clear the massive amount of air that it needs to clear through the hardlines to injectors.
I only wanted to start the motor to confirm it's condition before pulling it out. I will eventually swap a 603 pump on it and install in my w126 so I had not planned on investing in anything w210 related.
Short of a new key and ignition unit it goes into, what other steps might be taken to allow the car to start? Is there a way to jump the pins on the shutoff solenoid?
If unplugged, does it default to open or shutoff?
