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! |

White smoke and rough running can also be an indication that your pump is over advanced.
Be careful with running the engine (at all, especially under load) unless you have verified for certain that your timing is correct. |

QUOTE(BMartin914 @ Jul 2 2007, 09:27 AM)  White smoke and rough running can also be an indication that your pump is over advanced. Be careful with running the engine (at all, especially under load) unless you have verified for certain that your timing is correct. How do I verify this? How far would make a difference; the pump is only off one tooth one way or the other and the teeth are pretty fine (many of them/small adjustment). Total allowable adjustment on the pump is about 10* If it is off of adjustment, how do I know when it is in? I am very certain that I have air in the lines as the pump was out of the car, empty, and the car was parked up hill causing any residual gas to pool back in the tank. I used the hand primer to get it started (took a looooong time). I can crack the fuel lines, I know they had air in them as they were left on the pump. Messix, unfortunately that forum is hard to get info out of on a 75 115, IIRC (IMG:style_emoticons/default/dry.gif) I can try again. |
