2000 ml320 - PeachParts Mercedes-Benz Forum

Looking for a little help please ................. my 2000 ML320 is stalling sometimes , there was a couple of times with in the last year that the car didn't start , after 5 to 20 minutes it started , I always thought that I was hitting the gas pedal and flooding it , this happened about 6 to 8 times in the last 6 months , ....... within the last couple of weeks the water pump went , I took it to the local shop and they installed a new water pump for me , a few days later I started having the starting problem (( It would just turn and turn like it wanted to start but didn't )), one day I was in the middle of the road and it just stalled , I tried starting it and nothing , I thought maybe my car was low on gas , but it read 70 miles left , after about 20 minutes ,someone helped me with some gas , I went and filled the gas tank up and started to go home , once again it stalled on me , I waited about 20 minutes and it started back up and I made it home , the car sat for a few days in my driveway , and yesterday I tried taking it for a drive , it started right up , I got on the highway , got off the exit , came to a red light , stopped at the light, and the car stalled on me , I tried starting it about 5 times in 20 minutes and it didn't start , after another 5 minutes it finally started , I drove it all the way home without ever letting up on the gas , even when I had to stop I put it in netual , and I made it home , .................does anyone have any idea's ???? I did notice that on the speedometer , it had a wrench with a -300 in it , ((sometimes it appeared there )), does that mean something ???? is it a code of somekind ?? , did the guy who put the water pump in do something wrong ?? could it be a clogged fuel line ??, should I try some of that fuel injecter cleaners when filling the tank ?? could it be the fuel pump ??

Thank you for all who reply

Stalling and re-starting after a cool off period sounds like the classic CPS fault.

whats the CPS fault and is it expensive ?? Thanks

CPS is the crankshaft position sensor. Its a common failure on the 112/113 engines and exhibits the exact symptoms you describe.

under $100 for the parts, Medium difficulty DIY job and a E8 Socket is required.

and the wrench with the -300 means you're 300 miles overdue for an A-service

A new CPS costs about $75 or so from ********az. There a couple of different ways to change it. I have seen them posted on benzworld. I would do a search of this forum and of the other one as well.

Thanks John Hef......................and the wrench with the -300 means you're 300 miles overdue for an A-service

Just the minor one. Change the oil, top off fluids, check/lube a bunch of stuff and thats it.

Once you do the oil change etc remember to reset your FSS. Instructions are in the owners manual.

my 00ml320 stalled on the road last sunday night. tried re-starting and the engine cranked-over a long time and still did not start. when tow driver asked me to start it, it started w/ check engine light(mil) on. less than a minute after starting, stalled again.

towed it home and started on the driveway & able to park inside the garage. would like to get your advice(s) first before the next move. if i can fix it myself, i'd love to. thanks in anticipation for your reply.

driving my 190e for now.
