After installing the rebuilt 102 engine in my 88 190e the car won't run for more than 5 seconds...Turn the key off...wait another minute...runs great for 5 seconds.. OK.

This is strange. The engine was getting fuel before the rebuild (it was rebuilt due to a burned piston of #4 cyl...whole other story)..and all I did was take the intake manifold off the head before I took the head to the machine shop. The intake manifold, complete with the fuel distributor was stored in the shop. I DID remove all the injectors and replace the seals ..and the lines were removed from the fuel distributor for that time. Is it possible that dust or dirt entered the outlets of the fuel distributor and now it won't "distribute"?

Also, when I cracked all the nuts on the top of the FD, pressed the plate down all the way and had a helper crank the engine, there was a flow (slight) of fuel out all four holes...not a pressurised stream that would shoot into the air...more like a dribble..significant?

I know I'm getting fuel pressure because with the engine cold, left overnight, I pushed the sensor plate and it was quite a lot easier to move than when the system was pressureized by turning the key ON and waiting for the fuel pump to run for a second or two.

Silly Question #1: Does this system have to be "bled" like brake lines when run dry after uninstalling and installing?

Silly Question #2: Why does the engine start and run fine when I remove this plug (bolt) on the FD body (see picture)

Silly Question #3: What does the "Electro Hydraulic Actuator actually do, and can a faulty/badly installed one cause the symptoms I am experiancing?
