Where is the K-40 relay and does it have another name? I can't find it on fastlane.
Both filters have been replaced twice. I replaced the O ring on the filter bolt a few weeks ago, but simple to check. I will double check about the O ring at the S/O valve. Thanks for the help, Terry.

Am at work so dont have any details handy, but, it is the front most unit in the emissions box on the right rear (pass side) of the engine compartment. The part number starts with 210 540 xx xxx.

Cal-
This may be the only question I can ever answer on the forum, but at any rate the stock number for the K-40 relay is 2105400372. It is special order so you will have to ask for a quote. Mike |

Thanks for the part number, I'll pass it on.
Latest I have heard, and this was 10:00 yesterday, was they were talking of rebuilding the fuel pump. Is this pump even rebuildable? Could this be the problem? I was talking to the service writer so he may not have had the straight info. Today I will talk to the tech.

Order using your vin as there are multiple part numbers for different years.
I get 210 540 00 172 for the 98/99. Len rebuilt his lift pump. Was not difficult as I recall. One or two orings to separate engine oil from fuel. I doubt it is your problem.

And now the latest chapter in the long, long saga of my Benz. Stopped by today to see what was going on, this is what the owner told me:
1. Replaced all the fuel line O rings again 2. Fuel pump is part of injector pump, its one unit 3. Starts better now but still not right 4. Only thing left to replace is the IP ($1675) and can't guarantee that will fix. 5. Need "ultrasonic" diagnostic machine that only some MB dealerships have. 6. They have done all they can... 7. Will charge for parts installed and a small percentage of the labor. I plan to bring it home and drive it as it is, if at all possible, and fiddle with it myself. I'll try some of the diagnostic techniques you all mentioned that they didn't. Boy, I tell ya... driving an 87 with a bad turbo is gettin' old. Wish me luck...

Smoke tests and now ultrasonic testing too. New stuff.
See #250. Is exploded view of parts kit for rebuildable fuel pump/lift pump mounted on side of IP. Its not part of the IP rather attached to it. New one costs ~$125. http://detali.ru/cat/oem_mb2.asp?TP=1&F=210025&M=606%2E962&GA=722%2E608&CT=M&cat=19T&SID=07&SGR=045&SGN=01

I just emailed Phil, he got me a quote for the fuel pump only, $154. Is this something I can do myself? Looks rather simple.
Thanks again Terry

Just the fact that they don't know what they are talking about with respect to the fuel pump would be enough to tell me to get the car out of there, fast. The fuel pump is attached to the side of the IP, it is not a single piece together...you will do better with the help of this board than these so-called professionals would do.
For the heck of it you might consider confirming that all of the fuel lines are connected to their correct places...it is quite common for a tech to remove more than one piece at a time and forget which one went where...so use the EPC sketch and confirm that every line terminates at its proper point.

Quote:
Cal - Search Len's name "Sokoloff"(sp?). He started to do this job recently and ended up replacing the gasket only IIRC and putting the part into "inventory". Its a very simple pump design. It is also not a high fail part. I would invest in a new K40 first.

I don't know the extent yet, but what could they have done to make it better?
Terry, why the K*40 first? is it more likely or cheaper or both?

I would go through the last list I wrote and check the easy stuff first. Techs do make stupid mistakes too.....also check the fuses on top of the K40.
K40 is very easy to do, is fairly cheap, is a very high fail part and can cause all kinds of electrical gremlins. The K40 relay took the place of the OVP on the W124 and earlier models.

I'll give it a try. You think the K40 is screwing up the shut off valve?

Look at the other stuff first and get your fingers wet.
*************** The K40 can def affect the S/O valve, causing the valv to close prematurely (causing immediate shutdown) or to fail to open (causing no start). K40 fails when pathways on circuit board crack and lose conductivity. Typically is noticed as intermittent type failure of OTHER components powered by the K40. Is possible yours is failing and that it only causes a problem when hot and the circuit board has expanded, openning the cracks such that they no longer conduct. You can take the bottom of it apart and examine it with a good hand lens and possibly see lines or cracks across the circuit pathways. Some have soldered them back together too. Too tedious for me.

Terry,
I'm waiting for a quote from Phil on the K40. I think I'll triple check all the O rings first. then the K40, then maybe the S/O and fuel pump. Can I replace the fuel pump with the IM in place? I'd really rather not remove it, my tools/skills are limited. And if I screw up I'd really hate to take it back to the same place. You mentioned the k40 can cause quick shut offs and slow starts. In the case of the latter would it allow air into the fuel lines or would it just not open completly?
