Chrysler 300M Starting/Stalling problems

Hello there, I own a 99 300M with 207,000 kms on it. A 2.7 model for Belgium. My problem is on starting. For a few days no problems. Then when I turn the key some of the warning lights will come on some not,they flash all over the place, but just a click no fire up.The over head interior lights glow but very dimly. The battery is just fine so thats not the problem , but what is the problem ??

Any help for mthe other side of the pond would be appreciated. Basically I think the 300M is one of the better big cars I have owned in terms of looks space etc. However reliability does not seem to be its strong point. Kind regards Kevin

I will probably leave the car for a few hours maybe a day and it will start. Then it might work for a week without problem maybe less.


  • I have a Chevrolet Trans Sport 3.4 V6 from 1999. Recently I put in an other engine and transmission. After that both cooling fans did not work. To find out where the problem was I checked all the fuses (remove and put them back). After that I checked the relays first outside the car later inside the car by activating them making contact to the frame. At that time the fans start working :) . Then I needed to move the car and found out that a new problem was there :cry: . The engine was turning but the fuel pump not. Also I had no ignition on the spark plugs :confuse: .

    Does any one have an idea how to solve this problem? Did I make a mistake by removing all the fuses one by one? If I mixed up the computer, is there a way to rest the computer of the car? As far as I know all the other electrical equipment is working.

    I have a '06 300C and it has stalled three times in 16 months. The first two times, I was able to re start the car. Yesterday, it stalled and could not get it started. The dealership claims they cannot duplicate the problem, now they have the car unable to start. Maybe they can find the problem; however, it is very unsafe to drive. All three times it stalled on busy highways, I have been very lucky.

    You may get an answer on this group but you really need to post your question on the 300C group. This is for the 300M model in production from 99-04.
  • My battery went dead about a month ago, i replaced it. about 3 weeks later the starter went out and had it replaced. The mechanic had to try 3 different starters before one finally worked. 3 weeks later we are back in the shop and they have no idea what the problem is. They have now gone thru several starters, replaced ground wires from battery and turned crank manually to make sure that the engine has seized. no answers, no ideas, no car. HELP!

    Over the past month, my 2000 300M w/about 70,000 miles has gone completely dead three times. I drive for a while, park, and shut it off, and there is no power at all. When I try to restart it, some of the instrument panel indicators come on but the interior lights, locks, etc. are dead. I installed a new battery after the first episode, but it is still acting up. The first two times, I tried several times over about 15 minutes and it just started. I did not wiggle any wires or move the shifter or anything. Today, I tried for about 5 - 10 minutes and still nothing, then I wiggled the battery cables, shifted in and out of park several times, and still nothing. Finally, I held the key in the start position and wiggled the shifter and it started. Maybe coincidence, but I suppose it could be related to an interlock, but why would it cause a total power outage? Any Ideas?

    Bad relay or fuse block?
  • Not sure, but it happened again today. I parked the car and when I went to get out, I noticed the interior lights did not come on when I opened the door. I noted the time on the analog clock and left it for a few hours. When I came back it was fine, but the clock had lost 15 minutes. While driving home, the fuel gauge kept dropping to zero and back to 3/8. Almost like a loose ground somewhere. Guess its time to start checking connections.
  • tayl0rdtayl0rd Posts: 1,926
    Yeah, have that checked and also have the dealer check the Body Control Module (BCM). That might also be the problem. A few '99 and '00 Ms had the BCM go bad.

    My 2004 300M has stalled twice in the last few months while my wife was driving it. She stated that when it stalls, the steering wheel locks up and the vehicle will not start until it's back in park. This has only happened twice, but to me, once is one time too many. If anyone has any info on this issue, please advise on what it may be and how to fix it.
  • i'm trying to remove the analog clock from my 2000 300m and was wondering if any one knows how to do this with out causing damage to my dash board.
  • Hi. Its real easy just be careful. the whole vent cover pops off. there are clips at about 10 oclock, 2 oclock and 5 and 7 oclock I just removed mine monday 3/12/07. I actually used the round end of a bottle opener (church key) to pry it off and had no problem. The clock unplugs and also pops out.GOOD LUCK if you want to replace the bulb . its easy to take out. theres a little phillips type screw in the back of the clock a little twist and its out. I say good luck because my dealer cant seem to figure out the part number for the bulb. My light has been out for over a year and I finally took the chance (succesfully) to remove the vent cover. the bulb supposedley cost under 2 bucks. to replace the whole clock is $150.00 (Crazy huh)If you are trying to replace your bulb and you can find one I would appreciate if you would write me back with the info @: Good Luck And thanks in advance
  • Thank you i tryed to remove the vent and was shocked how easy it was. I will try and find the part number on the bulb and get back to you thank you.

    My '99 300M died on the freeway in '06, dealer couldn't find a problem, no computer code. A mechanic friend said no code from a fuel pump OR fuel pump relay (under hood).. $10 replacement for the relay has seemed to fix it. Now one year later, transmission went into "limp-home" mode.. checking it out now at the dealership, not expecting much from them.

    Does anyone know where I might purchase a replacement for the 300M's ('99) analog clock? Mine died and the local dealership wants $165 . . . for a plastic analog clock!! Surely there must be a less expensive retailer out there.
  • bisbee2bisbee2 Posts: 5
    My car ('99 300M) went into limp mode as well a few years back and was stuck in 1st gear. The dealership replaced some tye of transmission control module. I've read of others having the same problem.
  • dgrams1dgrams1 Posts: 7
    got a call from dealership, 2 modules + 1.5 hours = $192 to fix transmission! Nothing wrong with trans only the modules to keep the computer happy. Isn't technology wonderful? NOT!
  • I have a 2000 300M that has had a starting problem sporadically as well. It does the same blinking lights resets the seat memory but not the radio stations and ejects the cds. I ran a diagnostic on the car and the only code I am getting is error P1796 Autostick Input Circuit. I went through every diagnostic test I could and it doesn't even show a missfire (I tested via computer everything from the lights to body sensors. I am wondering if any one else can find any information on this code as all I am getting is generic sensor error or possible manual overheat.
    Anyone have any ideas or in formation?
  • My 300m recently began dying right after I start it. When I start it the engine will briefly flair to a little over 1000 rpm like it normally does, but when it settles down to the normal rpm, it goes too low and dies. Once I manage to ease the rpms down to the normal level it will be fine and will not die the rest of the time I drive it, although it the rpms will bounce up and down if I am moving at parking lot speeds and let my foot off the gas. This does not seem to happen on the first morning start of the day. This started happening after one of the following two events(I am not sure which one caused it) 1) I disconnected the battery for a bit 2) I left the engine idling for about 40 minutes. The next time I started my car it behaved as described above.

    I have not cleaned my TB yet, but I feel it is not real likely to be a problem since this issue started so abruptly.

    Does this sound like a crank or cam sensor or anything?

    Thank you

    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"...

    I am in the same situation with a 2000 300M - have you come across a cheaper option to replace the analog dashboard clock?
  • 2000_300m2000_300m Posts: 4
    no im sorry i dont have any options for you maybe try ebay or something like that
  • klm1959klm1959 Posts: 1
    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,
  • 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.
  • I have the same exact problem - the mechanic is stumped - had a tune up done seemed to be good for a few days now having same problem - the car is going to dealership tomorrow to be dx'd they said maybe fuel pump
  • did the stalling continue if so what how was it fixed?
  • Hi Robin The stalling was a bad fuel pump which I ordered on ebay and dropped the fuel tank and installed. problem solved now over a year.
    I had the crank sensor on a Co .
    My wifes Concorde had the starter go out last yr and cost $400.
    I also replaced the electric radiator fan on the 99m last yr -again off ebay and did myself.
    Both cars now at 110,000 and doing well.
    PS when the window sticks I bang on the mid door while holding down the button and it comes down.
    Good luck with yours --these forums are a great help.
  • That should have read
    crank sensor went out on Concorde and 99M.
    Starter solenoid contacts on both cars
    Good luck Roger
