103 Stalling and not starting when warm...
It will not start until cold and then you repeat the cycle again. This happened to me while on the highway. No warning. It just died. I had to way until the car cool down. Luckely, it was a cool night so made it home. I did not noticed a faint SRS light going on and off. However, my A/C blower was also making a sound (I changed the brushes since then and no more blower sounds.) After that day, car continues to function great when is it cold but, as soon as it warms up. It starts acting up. The last time this happened. I crove the car for about 20 minutes with no problems. I went to the store for about 20 minutes. When I came back, I started the car and it run poorly like if it was missing a cylinder or two. The symptoms where worse when I tried to accelerate. I barely made it home (less tan 10 minutes away) going about 10 miles per hour. When I got home I disconnected the electrical connections (one by one) to the EHA, ICV, water temp sensor, check all the fuses, removed and reinstalled the OVP, Fuel Pump Relay. I tried to start the car again after each item was removed. The car would not start. All the instrument lights were on. One thing I did not notice before is there was a clicking noise behind the instrument cluster when I tried to start the vehicle (Hall-effect speed sensor?). That was about a week ago. Today I started the car on the first try. Running fine while cold. While researching, I know it could be a number of things like OVP, Fuel Pump Relay, Crank Position Sensor, coil, etc.
By the way, I tried a different FPR with no improvement in the problem, I suspect this is electrical...Can the Hall Effect speed sensor stall a car...? What gives...?

i had this same exact problem, it was the crankshaft position sensor in the rear. find my thread if you need more information

Did you test the CPS...
or just replaced the part.?
How do you test the part...?

Here's some test results for our W201's just for reference. http://www.benzworld.org/forums/w201-190e-d-class/1419951-crank-sensor-test.html

According to that link...
my CPS is within specs while cold. However, the car started fine this morning and now it will not start. I did disconnect a few more things before I try starting it again. I double check and now, when I disconnect the water temperature sensor (WTS) wires, in the back of the engine, it will start but, it will die after a couple of seconds. When I reconnect the WTS, the car will not start. I think we are getting somewhere here. I now need to test the WTS and see...I hope it is not a separate issue...

On ours I replaced the CPS, and both temp sensors, and its general operation improved greatly.

Hall Sensor, Crank Sensor....
Hi J.HIDALGO,
Hummm, Stalling issue...? The one who will be able to tell you change this part and your trouble will be gone in the world of Sudden Stalling Syndrome (SSS), isn't born yet. The part who might stall your car are to numerous, from a defect alternator to a fuel pump and all the parts in between, it's almost a bumper to bumper situation. Symptom might look the same sometime, with different issue. On a more positive note, with dedication and procedure we can isolate and find those Gremlins causing SSS. Do not start throwing parts at diagnostic, unless you're lucky, this will get you no where. The first step in Sudden Stalling Syndrome world is to be able to read the diagnostic socket MB give you, it take me three years to figure that. Well, I'm slow..... View this Diagnostic Socket as windows to see how your car feel, your car talk to you by those Windows. The tools you need are not expensive and will open the windows. You need to be able to read duty-cycle from the X/11 socket, you also need to be able to to read a pulse code reader for the X11/4 socket. All depend year and model of your car you will find the spec. in your shop manual. You also need basic knowlege in mechanic. You will find plenty of help here if you can come up with info from those windows. Other than that find a good shop, you trust and let them do the work, but please ask question.... Don't let him throw parts at Diagnostic. To answer your question: Quote:
The only problem the symptom don't fits... "Engine Stumbles or cuts-out when coming to a stop, engine idle surges intermittenly" You see what I mean?? Max

Fuel pressure
Did you check fuel pressure and for leaks in the fuel system?
Recently solved a stalling problem in the 1991 190E 2.6 by checking fuel pressure and saw that the pressure wouldnt hold and sure enough it was leaking @ the fuel pumps.

As mentioned above...
Things just got worse. Now I have a start and die after only about 5 seconds. I wonder if both situations are related...I have not checked the fuel pressure but, if there was a fuel leak...why would it die in the the middle of the highway and would not start until the engine cools down?

I did notice today...
the wire from the distributor to the coil has some marks on it...I will check tomorrow...

I would check fuel pressure though only takes like 5 minutes. To answer your question if you have a fuel leak it would die because the fuel pumps cant keep up and fuel pumps would try to build up pressure hence not starting right away.

Hi there,
I suggest you; Test the distributor cap With the meter set to measure OHM's (resistance) measure the resistance from each terminal one at a time with one probe in the centre of a terminal at the outside - and the other probe on the same terminal inside the cap. RESISTANCE SHOULD BE: 700 to 1300 OHM's Test the rotor at the middle (where is contacts the centre cap terminal) to the outer peak. RESISTANCE SHOULD BE: 700 to 1300 OHM's Test ignition cables and the spark plug connectors RESISTANCE AGAIN SHOULD BE: 700 to 1300 OHM's Also your suspect main cable from the coil to dist cap. Replace any component outside these specs. Good luck, Acky |

I checked the suggested parts...
and all of them are within limits. However, inspecting the coil I noticed a faint white spot behind the coil's metal bracket. Can you test the coil with a multimeter?

I would start by actually replacing the OVP if all the instrument lights are on. Sometimes the fuses are absolutely fine, but the unit itself is shot. If it has never been replaced before in its life, then it probably time considering your stalling. The other possible culprit would be the voltage regulator attached to the alternator. These two, to my knowledge, would be the only items to cause illumination in the cluster. Start with the OVP then move to the voltage regulator.
I had the same stalling problem on my TE until I replaced the OVP. I also checked the fuses on it and it would just die randomly on me while driving.

Sounds like you are having some of the similar problems that I had. I have a 91 300E. Check out my thread "Owner of a 91 300E looking for a cliff"
I replaced several things all of which temporarily helped but i now suspect they just needed to be replaced as maintenance. I replaced...
*I replaced the fuel filter twice, Once a couple hundred miles before a, once during the pump replacement. Hope it helps.
