Re: 300E Fuel Distributor

My 300E won't start. I have fuel pressure because if I loosen the fuel line to the cold start valve i get a shot of fuel spray from it. So the fuel pump is outputting. However if I disconnect one of the fuel lines to an injector and crank the engine, no gas is ejected from the fuel distributor. What we be the problem with that? Thanks for your help.

The injectors are working continously. They spray fuel on the outer side of the intake valves.

During cranking the injector line is closed because there is no vacuum behind the thottle.

During start (with normal temperature at engine) fuel is supplied for 10 sec via the start valve.

With very cold engine the injector line is opened by the cold start idling regulator by vaccum too.

The normal supply needs running engine, vacuum build up in the intake manifold and a floating air flow sensor plate in the air stream at the top of the fuel distributor to regulate the air/fuel mix.
