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..
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"? I also recall removing and installing the Electro
Hydraulic actuator at that time as well....
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 SOME 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. Is it enough fuel pressure? Is
ther a way to tell without putting a guage on it? (which, I have heard, will
damage the FD by blowing some seals?)
Silly Question #1: Why does the engine start and run fine when I remove a
screw in plug from the side of the FD body? This plug is an M12 head bolt
about 3/4 inch loing located just below one of the injector outlets
Silly Question #2: What does the "Electro Hydraulic Actuator actually do,
and can a faulty/badly installed one cause the symptoms I am experiencing?
Silly Question #3 can this whole thing be just a dirty fuel filter? The car
did sit for 3 months indise a heated garage while I had the engine out.
