Sorry, I haven't updated this thread in a while, since I was busy with school
Also it blew another glow plug wich was getting annoying, so I ordered four new ones, and today it finally STARTED UP again
I did however run it off a can of diesel purge, and it started much quicker on that than with the normal fuel line connected to the tank.
My thinking is that either the diesel pump is shot, or the fuel line is plugged/has a leak. Doesn't matter, since I plan on replacing ALL steel lines on the car eventually.
My biggest concern right now is the surging at idle speed, wich is quite hefty.
I'm going to measure the fuel consumption at idle again on the weekend, because it still smokes black like crazy, and I suspect that there is way too much fuel injected.
Edit: I forgot to mention, the smoke signals the diesel produced attracted a arab fella in an audi A6 who wanted to buy the 200D/My Mum's Opel Combo/My 230E, to all of wich I responded with no.
Edit2: I inspected the Diaphragm both visually and with the 'thumb on vacuum line connection method', and it seems to be ok
