CLK Quits 3-4 Min. After Cold Start, Then "Heals"

Hello:

I have recently acquired a 2001 CLK320. Car is very nice with but a few minor instrument issues and some small stone chips. After buying car, I climbed in and drove it 900 non-stop home with zero issues.

Since then, upon each and every cold start, the car runs fine for 3-4 minutes then 'quits' / 'stalls' dead without ANY warning signs or apparent reason. Same thing EVERY time. Car will quit after same time period even if idling in driveway, or at exactly the same marker point on the route to work.

Leave the car sit for between 5 and 45 minutes and it will restart perfectly, instantly and run perfectly for the remainder of any day, including stops, short shutoffs and any other typr of use.

There is absolutely NO symptoms before quiting, or when it decides to restart. Like a switch. The car will crank and crank with absolutely no stuttering, partial catches, backfires, nothing at all. It either is perfect, or won't run at all. No difference between night day, rain or shine.

This one has me stumped.

Any help or similar experiences REALLY appreciated.

Thanks.

Thomas

Welcome aboard. Please click user cp and edit details to add your VEHICLE and LOCATION to your profile, it's useful information when you're seeking help.

I'll admit I've never heard of a case such as you report. The first thing I would do is put a scanner on it to check for stored/pending codes as that is likely to point you to an issue. You might also search through the W208 forum as that is specific to your model, too.

Good luck.

+1 for an odd issue and having the car scanned. Even though you don't see any warning lights on the instrument cluster there can still be error codes stored in the car's memory. Several auto parts places do this for free or for about $50 you can buy a decent one. Actron is a frequently recommended brand.

"Classic description of a fuel pump relay. Very common in the W126 Section."

Thank you VERY much for all of your kind attention and recommendations. I should have mentioned that I have done quite a bit of wrenching over the past 50 years and after the first failure, I really strated to take note of all (emphasis added) symptoms, including preceeding and post-problem.

Also, when it finally re-starts it is absolutely instant, first touch of the key, first revolution of the engine. No rough running. No indication of lines refilling with fuel. Either runs perfect or dead, no in-between

Actually closed my eyes in a quiet location with all the windows open, started it and just 'listened and felt' while it quit.

I kind of ruled out a fuel problem any real distance from the injectors / injector pump as there was/is absolutely no 'stuttering' or 'partial catching' of the engine during unsuccessful cranking. There is also no backfiring, jerking or even the slightest indication of poor running before quiting, or upon restarting, (such as I would think would be the case as an injector pump picks up the remaining drops of fuel in a line going dry, or re-fills). Shuts off like a switch.

PLEASE correct me if this engine/fuel system has a feature on it that would overide this speculation.

I have ordered yesterday afternoon - 3:00 PM, (and received at 10:00am this morning ((!!!!!!)) ) a Crankcase Position Sensor, for $113. from PRIME MOTOR GROUP (highly recomended and Mercedes Factory Authorized).

I am going to attempt to install this sensor and will report the results back to the Board.

I have heard rumors of a special "adjustment" or "set up" routine required to get a newly installed CPS to function, but am UNABLE to get any solid details. Any knowledge of a "post-installation procedure" please ??

I really appreciate all of your attention and ideas. A great group.

Thank you. Thomas

Most of us are not fans of having to scroll up and down in a thread to get such basic info. Not to sound too rude, but it's the second time I've asked, and if you can't help in that small regard, there are those who are going to simply ignore your posts.

You have a CLK320, with the M112 engine. The re-indexing procedure is in the W210 help/DIY stickies, it's pretty simple and based on what you do after you restart the engine following the change.

Good luck.

Hello Greg210. I am really very sorry that I did not enter my location. I am brand new to the board and did not realize the importance of it. I have found the Control Panel and filled out all of the requested information. Very sorry you had to ask twice. I had a parent pass away last week and it has been hectic.

Regretfully,
Thomas

Hello:

I have taken the received CPS unit, a 1/4" drive, 1/4" socket and after placing a quantity of cardboard and protective blankets over the engine, climbed up, with a light, to remove the original CPS.

It was a bit tight but the CPS came out in a couple of minutes and, the replacement took a couple of minutes to re-align and get the torx bolt started. After re-attaching the wire and removing the cardboard and heavy blankets, the car started right up.

Complete job took about 15 minutes.

I have been testing it since then and so far it seems to have repaired it. I am extremely grateful for everyone's kind support, suggestions and direction. It is very much appreciated. Thank you.

Thomas

Greg:

I have gone to User CP as you asked and thoroughly, carefully entered all of the requested information. I hit save and did not see my changes / updates on the left of my posts. I have gone back to CP, re-entered everything a second time, ,checked to se that I did not miss some 'checkpoint' or 'confirmation' requirement and saved the changes again. Still no appearance on the Board.

Greg, I am very sorry about this and really don't know where to go about entering my location. I live in Niagara Falls New York and really don't care who knows, but I am obviously doing something wrong when it comes to the CP. Pls advise.

Thomas
