s430 wont start...help!!!!!!!!!!!

[klexgs]

hey guys, i have a slight problem with my 00 s430. last friday i went to my car to start it, ignition turned over but it would'nt start. waited a few hours and tried again and she started right up. i took it to a benz mechanic on sat. he said the problem was that the check engine light was on for so long.(this problem, was diagnosed from dec. that it needed an air flow meter). i told him to put in a brand new air flow meter, the check engine light still did not go off. he then tells me that there were 24 codes that needed to be cleared and he cleared them,during that time the battery died, so i bought another battery. the battery was for a c-class and i was not surprised b/c it is a used car. on sunday the problem reappeard. she turned over but did not start. after about a few minutes she turned back on. now this is getting ridiculous. on monday i tried starting it @ 9am didn't want to turn on. she finally started @ 10am. on my way home the engine shut off completely and i sat there for ten minutes, then she started. i feel that it is an overheating problem or an electrical problem.today i discovered that when the temp gauge is between 80-100 degrees it won't start. i'm the fourth owner and the car has 112000 miles. i bought it @ 90000. thanks for your responses. help!!!!!!!!!please

Get a better MECHANIC!!!! Is there a default in there somewhere that prevents it from starting at less than optimal battery and alt levels?

I had a very similar problem with my 2000 S500....sometimes it would start...sometimes it wouldnt....mechanic couldnt figure it out...wasnt the crankshaft position sensor.....two tows and two trips to the shop later (and a new battery) we figured it out.....the key was not "communicating" properly...try turning the key to the on position without trying to make it turn over...leave the key in the on position for a couple of minutes..the key and the car will communicate with each other...then turn off and remove the key....put it back in and see if it will work....kinda a long shot, but this would be better than putting a new crankshaft position sensor in!! hope it works!! let us know...

thanks guys, i appreciate all your responses. i've already tried the key in the ignition for two minutes but the problem persists. the next thing for me is the crank positioning sensor. 'preciate those comments, keep em coming.

I have the same problem with my 2001 S500. It stalls and won't start anytime whenever it wants to... feel so bad many time on street, intersection.... Can we replace the CPS sensor by ourselve? And where it is located at?
Thanks.

I tried your trick and it worked...

I don't recall ever chainging the bateries in my key remote,
maybe that's all that it needs, will do and let you all know if this works
for me before paying another $82.5/hr to have a mechanic tell me that
"they cannot develop the problem" and send me home again with the same
problem..."

Will be in touch,

I have the same problem with the exact same mercedes. Now my car battery has died because we never drive it because if we drive it it might not start when we try to leave our destination. Does anyone have a solution to this problem? Is this a crank position sensor? Or something more serious? How much is the part? Can any mercedes shop fix this?

mcavs, I'm having that problem at the moment! Will a new key or new battery fix this?
