Chances are that you have a vacuum leak, that you will need to find and fix. Most likely a leak associated with your central locking system. Probably at one of the doors, and most likely with the vacuum hose associated with the driver's side door.

In the interim, until you locate and fix the problem, you should not need to pull off a fuel line to shut off the engine. You don't say what year your car is, but you have either an emergency shut-off valve, or leaver that you can use for this purpose.

No year info, but I believe all Mercedes diesels have a manual level on the top of the engine, somewhere between 3rd and 4th cylinder with the sticker "stop" on it.
By pushing that sticker you'll kill the engine.
Than check all the vacuum lines for disconnected tubings. Finding leaks on the door locks is hard, because lines go under the floor mats and inside the door, but you can find the tubing, that goes thru the firewall, right behind oil filter and plug it. This way you have all still working vacuum tubing visible under the hood and after fixing the leaks the vacuum kill switch suppose to work again.
Hard start-up is very likely some of the glow plugs burned out. Need model info, to be more specific.
Good luck.

Shut off valve is probably leaking. A shop can replace it for around $100. The valve is located under the shutoff lever, which you can use to shut off the engine.
If you're handy you can fix the valve yourself.
