    My wife's 2003 C320 is having the same problems. Sometimes the car keeps on cranking but it won't start and on two occasions the car stalled at the traffic light. We're not sure if it's due to crankshaft position sensor failure but it's very annoying because you dont know what the car will stall. Can anyone tell us the cost to fix the problem? Thank you!

    In the morning the car would start fine. After driving about 20 mins. and turing the car off, if will not start up again. I would have to let it cool off anywhere between 5 - 8 hours. Took it to a mechanic, said the fuel injectors were "going" bad, and it would cost $1,400.00 to replace. I declined his service. Since then, the car will stall out at a light, or even while driving. Took it to Advance Auto for free diagnostic. The codes that came up were P0335, P0123, and P0456. I want to fix and keep the car, but I can't afford to spend $1,400 to fix it, and beside, I don't really trust the mechanic's diagnosis.

    This happened to me twice today. The second time it had to be towed to the dealer. It puts a sour taste in my mouth being I only purchased this car a month and a half ago. I love the looks and the ride but not the problems nor the price to fix them....

    chk eng light came on, hooked up code reader ( adv autopart ), bad crankshaft position sensor.
    car will not start if engine hot.

    replace crankshaft position sensor about $40. Took 3 hours to find it with on line pictures aid, and 30 minutes to replace

    I have been having this issue for about a month when I start the car but when I restart the car, It may or may not work fine. Hit or miss. I am taking my car to the shop this weekend.

    I have the same no start problem and changed the crank position sensor, but now the car will start at the first crank , idle for few seconds and turn off, so I try new feul pump relay and the same problem continue,however, if the car is warm then it will start at the first crank, just when it cool off I am having this problem.
