Freightliner FLD year 94 dont stat and sotp

Freightliner FLD120 year 1994 12.7 detroit my starts and stops:
I invite you to watch a video recording to youtube to see if someone can help me.
Not if I press both buttons to start and the override or only to start.
After the engine starts and immediately stops, diesel installation is disconnected and fed only with a bottle of diesel directly to the pump is behind the compressor.
Can someone help because the truck is in Spain, not many people know how these trucks work.
Thank you very much.
The video is this:

I do not speak English well and this is translated by google, sorry.

We have tried to launch seven years after this standing, we have only connected a bottle of diesel to pump directly but very bad sound starts and stops, the oil level is fine, the antifreeze also.
But after many attempts I was left by not doing harm to the engine, here in Europe the trucks run on 24 volts and this in particular is at 12 volts, but not how many battery leads and that power each, so we tried two of those here but 12 volts and turns right.

 

Ok thank you very much, I will continue investigating.
At switches 2 and 4 cyl should be up or down?
As I can disconnect the jake brakes
