Managed to view the vids, With my few years of high pressure common rail diesels, mainly Iveco and Chrysler/Mercedes, that sounds like an injector that may have something stuck in it. The stinky smell of partially burnt diesel is quite distinct. Starting on no heaterplugs will produce the same smell.
Have you stethoscope'd injector #6? Just to make sure it is that. Just a screwdriver resting on its body will tell you if it is that. A sound of a tight valve may produce a different sound. You have 5 other injectors to compare sounds to.
It could be a carryover from #5, and hopefully it can be dismantled and backflushed. Substituting may work. Its better than running it like that.
As for the pump situation? I haven't got a clue, but putting a non turbo pump on a turbo will probably just flatten the car unless you plan on driving it wherever very gingerly.
