"don't run it any more than it takes to bleed the injectors" (IMG:style_emoticons/default/blink.gif) (IMG:style_emoticons/default/confused24.gif) So, when the injectors are clear....stop running it? (IMG:style_emoticons/default/wink.gif) How long should I wait for it to clear? I'll try the crack the line method. Seems straight forward. Adjusting the pump is not an easy task. There are only 3 nuts, but the bottom one is blocked by the primer pump...which has 2 nuts that are hard to get to holding it on....and requires blood to get off...and oil and gas goes everywhere (IMG:style_emoticons/default/rolleyes.gif) This was not supposed to be a project car (IMG:style_emoticons/default/dry.gif) |

QUOTE So, when the injectors are clear....stop running it? How long should I wait for it to clear? He means not to run it until you are ready to purge the lines. Start it up and get to work. When you are done purging (this is sounding like and anorexia forum) the engine should be running properly. |

Have you checked the fuel pump timing? I just sold off my 240D stuff, including the fuel event timing nozzle. To change timing, you need a crowbar.. (I love the Germans).... You loosen the mounting nuts, then pry on the pump using the block as a fulcrum. Advance/Retard as needed, the fuel lines will fight against the pump moving (they are rigid tubing), so you will need to slightly "overbend" to get the right position. Timing virtually NEVER changes, it really just necessary when you change a fuel line, or pull the pump (if the lines get bent while pump is off).

Another thought.
If you do the purge and still find it running a little off, check around the fuel lines for a leak (between the pump and the injectors) that may be causing the injector to not have enough pressure to open properly. Do this with a scrap of cardboard. Having a high pressure stream of diesel tear your skin and mix with your blood is not fun. |

Actually, the germans would rather you unscrew the metal fuel lines. Adjust the pump properly, then spend 3 hours bending the metal lines to match the new pump timing.
The crowbar method I believe was an american invention. (IMG:style_emoticons/default/biggrin.gif) |

If you think it is air in your lines, the simple procedure is to just crack the fuel lines where they meet the tops of the injectors. This will allow the compressible air to escape from the line between the pump and the injector. Be careful when you loosen the nut holding the line, because the fuel that is under high pressure can spray out hard enough to puncture your skin if you are right at the point of the leak. When you see clean diesel and no bubbles escaping from the nut, just tighten it back down and you should hear the engine smooth (for a diesel) and run like it should.

If you find that the diesel stuff becomes too much of a hassle, I can take that 300D off your hands (IMG:style_emoticons/default/biggrin.gif)

I think I would have liked the 300 a bit more, but the 240 is effective for what I use it for (IMG:style_emoticons/default/biggrin.gif) |

Well genius collective, I cracked all the fuel lines and had Noel crank the engine until fuel came out of all of them. Then hooked them up and experienced a smoother running more powerful running engine (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/smilie_pokal.gif)
Now for the new question: It is smoking thick BLACK smoke very heavily, how do I fix this? Will this go away on its own? Is this due to it not being run for a long time and maybe having previously uncombusted fuel in the chambers from previous failed attempts to start it? |

I would run it for a while and see. Can you adjust the amount of fuel this pump delivers externally? I know with some you can, the VW Rabbit for example. Turn the fuel up and it will smoke badly.
I'm just thinking out loud, but did this come off of a turbo model? |

As far as I know, the fuel can not be adjusted as the cam is set for what it is supposed to be. Not a turbo model, just a lowly 240 (IMG:style_emoticons/default/biggrin.gif)

i don't know much about benz but there should be a way to adjust the injector pressure on the pump or a regulator.

Its MFI, I cant find any such adjustment in the literature.
