300SL R129
300SL R129 1993 - Not starting. got fuel & spark.

Hello

Car is 1993 300SL R129 - Engine M103.984

my sl suddenly does not start after a week it has been standing unused.
before that it started perfectly.
battery was flat. changed it, tried to start - nothing. engine crank but does not start.

checked fuses at engine bay.
checked fuel pump - working.
checked spark - there is spark.

took spark plugs out - flooded with fuel.
put new spark plugs - still nothing. not even trying to start.

i opened the 1st injector to see if it get fuel pressure, it is only getting small drops.
my common sense tells me it should get high pressure.
the high pressure line to the distributor is pressurized.

should the injectors get high pressure? where should i continue from here?
any suggestions will be gladly accepted.
i honestly belive your experience with these cars can help me here guys

Thank in advance!
