Hi all,

I am having problems with my '99 clk320 not turning over when I try to start it so I did a search and found out this was a common problem, I bought a new Ignition Position sensor and installed it but I'm still experiencing the same problem, can someone please assist me, thanx in advance

sorry to hear about your problem. It could be the fuel pump.

By the way, did you install the sensor yourself? How difficult was it? If you did the install, could you post some instructions?

Thanks.

Sorry, but a friend installed it for me when I was at work, but can you explain the fuel pump thing, don't quite know how they connect, thanx in advance.

The crankshaft position sensor problem is actually when the car will turn over, but will not crank over to start the vehicle. What do you hear when you try to start the car?

Hey nick,

That is exactly my problem, it cranks but just doesn't turn over to start. I bought a new ignition position sensor and it's still doing the same thing, it seems to start perfectly when the car is cold but when the car gets hot that's when I encounter it cranking but not turning over, i'm wondering if I got a faulty sensor from the dealership.

Any assistance you or anyone can provide will greatly be appreciated, gets embarrassing, here I am with a benz that looks good and don't even start and a hyundai guy next to me jumps in and is on his way.

Is there a special way to install the sensor?

nickv

Unfortunately I don't even know what the sensor looks like as I didn't install mine. You are correct, the problem only happens when the car is warm. Sorry man, wish I could be of more help. Try PMing MBTECH208, he might be able to offer more assistance.

Hey nick,

When you changed yours, was that the end to your problem cause if it was, then maybe I need to change that new sensor I got? Thanx in advance.

nickv

Yup that was the end of my problems. Also, have you checked the voltage on your battery? I ended up replacing my battery before the sensor as I had killed it trying to crank the car without success. Good luck man!

I have the same problem too. I drive me crazy. Where I can get the parts? Price? Is it difficult to DIY?

Thanks

Not to difficult, you can get the part at any MB dealership for around $140.00
check previous message for diy instructions.

The sensor takes @ 30-40 mins to install if you have the correct tools. I paid $100.00 for mine at the dealer. Make sure you get the correct one for your car. MB used 2 types on the 208 body. The only difference between the 2 is the connector end. Read theses links......
