The crankshaft position sensor may fail. Symptoms of this are: The engine will crank—but not start—especially when the engine is warm. The car may start again if it is left to cool off, but it may run roughly or have poor performance.

It has not been fixed yet. When I turn the key, i can hear the engine "click" and make a stalling noise. It usually ocurs after I've turned the car off and try to restart after about 15 minutes. I typically allow it to "cool off" and then it starts up fine. Occassionally, I will hear a stalling sound when I try to start it in the morning. It will start, but it sounds like it's stalling.

My car shuts off after running for approximately 10-15 mins. It shuts off when i come to a stop. I had the battery and alternator checked. I was told i need a fuel pump,then i was told i needed a starter. None of these answers felt right. So i decided to research the problem and im glad i did. By reading the other post it will save me some time and money thanks.I will post later after i have the crank shaft sensor replaced.

the car stalls and won't start several times and it would not start sometime 30 or 40 minutes later, but still it won't go far before it stalls again.

Having the same issue, i've changed the battery, mass airflow sensor, and trottle position sensor, and still cranks and dont start, only after like 15-20mins. Then also another problem just came along, when it finally starts, it stays in 1st gear.

My ML320 would run hot and shut off while I was driving or at a stoplight. My mechanic put on new fuel pump even though I had gotten a fuel on April 27, 2009. Now he thinks its the crankshaft position sensor.

I must say the 2001 Ml320 is the crappiest vehicle mercedes every built - if the electronic window controller brakes about having it a year - the break booster needs replacement, the cam sensor and the gear box sensor simultaneously goes faulty - for this type of vehicle I must say had I known what I know now I would never have purchased this vehicle - and to add injury to all when writing to them on their website their responce was very sarcastic and snotty ... but then what did I expect - them to take ownership of the crap they produced ----

Axact same issue as reported here. Mercedes emergency service on site diagnosed problem. Auto started after cool down and took to dealer next morning. Replaced sensor by dealer fixed the issue. Looks to be a built in failure mechanism on this vehicle and an added periodic income for the Mercedes dealers.

The vehicle would cold start but would only crank after that. Replaced the CPS jumped the car and all is good.
