There could be several reasons, ALL of which I've experienced. 1. Check to be sure the tranny is totally in "Park"...there is a lockout that will prevent starting if it's not fully engaged into Park. 2. Try allowing the power to illuminate the instruments before turning to "start"...this may work and is usually the sign of something going bad... 3. If it takes multiple attempts to start the vehicle, likely the brushes in the starter have gone bad requiring at a minimum the replacement of those or more than likely a new starter. From what I'm told, this is a very common problem on the 300M series. ADDED: If the car usually starts when cold and tends to not start after engine is fully warmed, check for a bad crankcase position sensor (also called a cam position sensor). Often this is the problem.
solenoid is bad ,have it replaced,but check for remote solenoid first some vehicles have another solenoid mounted closer to battery
If the engine will not even crank, then suspect a defective battery or starter. Start by removing both battery cables and cleaning the cable connections and battery posts. Reconnect them and see if it starts. If not put a battery charger on the battery and fully charge it. If it will not accept a charge is is defective. It the vehicle starts then you may have a defective alternator. If the battery is good and it still will not start, suspect a bad starter. You will have to remove it and have it tested.
Your battery will become no good!
If the battery is good and the starter is good, then you must have a wire disconnected somewhere.
check ur battery any chain auto parts store will test it for free.
my battery is good but having problems with starting
Dead battery, disconnected wire, failed computer, failed fuel pump, out of fuel,
If you are using it to turn on the car a good battery would help.
it takes a group 75. a good battery would be an ac delco 75-60.
you can avoid draining the good battery
www.user-service-manuals.com/chrysler/index.shtml would be a good place to start. :-)
There are always two things to look at when a car will not start, petrol and spark.
