I have my 2011 in the shop for the same reason. So far they have replaced the relay and keys with no improvement. Now waiting for an ignition switch assembly to arrive.

I have a 2003 Ml 500 that wont start. Its cranks but will not turn over...Does anyone have a clue?

^^Well, first of all you're in the WRONG FORUM. Secondly, that is very vague information. It could be a lack of fuel due to a bad fuel pump or a clogged fuel filter. It can also be the immobilizer not allowing the car to fire because of a fault.

JenniferS · 02-09-2012, 02:19 PM

Sorry for being vague.. I can hear the fuel pump when I get under it and have someone turn the key to on position. I was wondering about the fuel filter too. Do you know where I can find the filter and waht do you mean no fire by falt?

Okay if you hear the fuel pump then it isn't the problem.

Do you smell gas after trying to start it a few times?

The immobilizer is essentially the entire anti-theft alarm system in your car. The Smart Key(the key fob) contains a chip inside that communicates with the car allowing the car to start normally. If the key is not recognized the car will not start.

If you crank the car and release the key after 3-4 seconds, what lights are on the dashboard? Like is the Check Engine Light on? or the Battery Icon, etc.

If you are not very mechanically inclined, hop into your car, turn the key and let it crank for a 3-4 seconds and release the key(DO NOT TURN THE KEY TO THE OFF POSITION). There should be symbol lights on your dashboard. Take a photo of the gauge cluster with either a digital camera or a smartphone and upload the photo onto here. I will look at it and try and help you further.

No I do not smell gas. And when I try to start it and look at the dash all lights are on..Even when I stop trying to crank it..

AudiA4Turbo22 · 02-09-2012, 04:20 PM

That's most likely an Immobilizer problem.

It is really difficult to help you out without getting the car scanned for codes.

I had an issue with my ML before where it wouldn't start. Not sure if it is the same thing but after a few minutes it started. The next day it did it again. Ended up being the crank shift position sensor and I needed a backup battery. It is far fetched since I don't really know what else is going on with your vehicle but that was my story.

Well its been a few months since I first repoted the starting issue... For what ever resaon back then it started up and ran fine all this time. Now today it has done it again.. I replaced the cam sensor today but nothing changed. Anyone have any ideas?? If not I guess I'm getting a scanner soon.

MinnBobber · 05-25-2012, 04:24 PM

Could you please describe what happens when you turn the key, exactly...

Does the engine turn over/spin rapidly but does not fire
or
nothing at all happens
or
there is a clicky clicky noise from the starter
or
something else??

Each has a different likely cause.

JenniferS · 05-25-2012, 04:45 PM

It tries till it stops. Not turning over at all.. It does spin and not fire/ turn over and crank.
