I would try to tow the car, hopefully you dont have automatic transmission.
If you first get it warm in a garage this would help a lot.

This summer I replaced the engine in my W110 and had a lot of trouble starting it, drained 3 batteries.
I also tried startgas but I got only one stroke with ignition.
Then I called a friend and he said I should try to tow it, he said even in the winter (northern Sweden) he had started his old 300d this way, so I did the same and 200 meters later the engine was running and has been since.
I checked and saw fuel coming on all injectors on this engine.
