Injector pump timing

[Dubyagee]

I need to know the correct method for setting the initial injector pump timing when installing a new timing chain on a 1984 2.2 190D Serial # 601.921.12.001571. The manuals I have read show timing marks for the cam and crank but no mention of the injector pump. It has become my mission in life to learn and assemble this engine correctly. Any help would be appreciated.
