Why does a Chrysler 300 not always start when you have a good battery and is in park?
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.
