This weekend has been very productive! All of my vehicles are at least turing fuel into noise. Now it is time to make it useful.
I put the fuel pump back in my Benz (it was out because I thought it was problematic). I adjusted the lever that actuates it and it now starts, but it runs rough. -White smoke -Knocks more than a diesel should -Has no power (less then before (IMG:style_emoticons/default/wink.gif) ) I made sure to NOT crank the engine with the pump removed and to keep the pump shaft from rotating so as to keep the orientation of the shafts in both correct. I may be off a little in my adjustment, but adjusting it will be a shitty task and I would like some veriffication that it is out of adjustment from someone more knowledgable than I before I go a bleeding all over the engine again. In summary: - Do the symptoms scream of any particular problem? - any advice? Thanks all! |

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.
