need to put a replacement on this weekend. found an exellent specimin in a junk yard for $40. easy to pull the old one (off an 89 300E that had been hit on the drivers side rear door area, which is good (bad) I think) but puting the new (old) one on I can't be so cavalier about procedures, must be careful, anyone ever tried this and what are the odds of success? thanks for any help...cliff

 

I have never been lucky enough to find a good fuel distributor in a junk-yard. I don't think there are ANY good fuel distributors in a junk yard. If the donor car was running before it was salvaged, and has only been sitting for less than 30 days, maybe.

I just replaced the Fuel Distributor on my 1992 W201 190E 2.6.
Reason: Car start up fine right away but for the initial first 15 sec. or so, engine would sputter when revved up. I brought it to a mechanic and was told, it could either be due tobad fuel Injectors, or, due to a bad Fuel Distributor. He was talking from experience saying he works on these cars a lot but he did not hook up any diagnostic instrument at all.
Results after replacement of Fuel Distributor: Car did not start.On the second day, I was able tostart it. However, there was excessive white smoke on the exhaust pipe. Third day, white smoke was gone. I was able to drive it to my independent MBZ garage shop. First thing they did, was to change the voltage regulator fuse/relay, asmall simple looking thing located close to the battery but a faulty one couldeasily causeout of spec. operationor a combination of things.They hooked up a Lambda tool to adjust to proper fuel and air requirements. They hooked up also a diagnostic tool so as to pull out any error code to pinpoint any component/s that could be faulty. I was told my ECU was not communicating and not sending signals and so could not bring out any error code. I have one spare ECU/Computer brain but did not have with me at the time. So, for $80.00 left the shop though they were not able to perform and come up with a result due to the ECU not responding.
Have read other forums and was told that the Lambda tool is a must when adjusting the Fuel Distributor. Experienced people would suggest that it would be better to bring your car to a MBZ shop to save yourself some headache as I experienced first hand. Iremoved and replaced2 fuel distributors 3x. Please follow the advise of more learned helpful people, I am no expert, just wanting to share my own experience. I do have a used rebuilt fuel distributor which looks to be a recent replacement, very clean, and I also have a used over voltage protection relay.

 

well it worked for me

 

Cliff, you saved yourself at least $2000. Congratulations!

 

Hey but Mine is probably shinyer!......right?....gulp

 

I must state, in all honesty however, that I did also install a new coolant temputure sensor at the same time ($35) and the old one (temp sensor) was totally crapped out so I may never know what the actual solution was....cliff (plus I did the reset that ohlord posted)...car is right again
