Try a new $7 fuel pump relay under the hood... Fixed my '99 300M after dealer said no prob to be found and got it started.. Leaves no info with the computer when it fails as either does the fuel pump.

Thanks for the reply. It turns out that it was a dirty throttle body. Although I didn't think it was because of the sudden onset of problems, apparently the computer had learned to compensate over time for the accumulation of dirt, but when the battery was disconected it lost that memory and was not able to relearn it. After taking the throttle body off and giving it a good cleaning, Everything is well again

Did you find the problem with this? I have a 1999 300m with 118K on it. Started having similar problem... lights all come on in dash, body computer comes on with fans etc... car makes a solenoid kind of click sound but doesn't start. Play with key, play with shifter, play with steering wheel, and after a dozen or so tries it turns right over. Battery tests fine and already just put a new starter in as my mechanic said the starter was developing "bad spots"...
thanks

I am in the same situation with a 2000 300M - have you come across a cheaper option to replace the analog dashboard clock?

ok, it's been about 6 weeks since you fixed your '99 300M with a $7 fuel pump. Have you had anymore stalling problems?
Thank you,

2001 3.5L Stalling Replaced Crank Sensor, But...

300M, 3.5L (2001). Replaced crank sensor but same stalling problem. Maybe a better description would help all you troubleshooters out there. Would appreciate advice on next try...
1. Never stalls around town, only after driving awhile at highway speeds, then only as I come to a stop.
2. As I slow to a stop, I notice the tach bouncing up and down around idle point, but just goes a little lower each time until engine dies.
3. Cranks right up.
4. Never stalls while at steady speeds.
5. Once I get back into town and drive at slower speeds for awhile, problem goes away.
6. Plenty of pep, good acceleration in town and on highway.
Any guesses what I might try next?

wasn't a fuel pump but the f.p. relay. Since then I've had to replace to sensors on the tranny as they went bad too. Outside of that, it's been pretty reliable. Nice ride and pretty well designed. I enjoy it, but only during summers. Sits in the pole building during Michigan winters.
