hotwiring necessary 1986 W123 turbodiesel

Hei!

I bought a parts car without any keys. Nice late turbo diesel with 200K miles that was stalled a year ago due to electrical problems.

The ignition lock is drilled out by me to be able to steer. I have been trying to hotwire the car to check the engine before putting it in my nicer 1984 NA 300D wagon.
So far it only growls one time(nicely though without hestitation) after glowing and starting. Then it only chuckles without firing.
I have been bleeding the diesel lines x times, maybe without luck.

What am I overlooking?
-Anything with the vacuum lines in the ignition lock? (I connected the two together)
-Or maybe more wires must be connected? (I took one of the two hot red ones, then the red w black stripe, then the purple starter wire)

617 Turbo Diesel Injector Part Numbers/Interchangability

I have 5 each of these injectors:

KCA30S46

KCA30S35/4

KCA30SD27/4 (this one had a plastic cover with the number NA32X on it)

Are they interchangeable?

Will the same nozzles work in all?

The cars in question are a 82 300TD Turbo and a 84 300D Turbo. I want to rebuild the injectors and want to make sure these housings can work with the nozzles for the cars. Thank you

1983 300D electronic speedometer conversion?

I replaced a failing differential in a 1983 300D which had a 3.07/1 final drive ratio with a w126 differential with a 2.47/1 final drive ratio. RUNS GREAT!!! Of course, what the tranny-driven mechanical speedometer-odometer now registers is about 80% of what the actual speed and mileage are. I would like the instruments to reflect actual speed and mileage.

In the original vehicle, an electrical speed sensing unit on the differential connects to the instrument cluster.
