A little red light between speedometer and gas gauge came on and it won't do nothing

a red light between speedometer and gas gauge ids possibly warning you of something important, ensure you have checked all the oil levels, brakes, engine, power steering, coolant and also ensure the automobile has been serviced correctly

Could be it not reading the key

You said it's not doing nothing? So in reality, it's doing something!!! Since nothing is what you said it isn't doing

So did you ever figure out the issue? My 05 300c has a red light on, fuel pump and everything engages, but won't start?

Go to your trunk find the fuse and relay box and pull number 5 and 29 wait ten minutes replace number 5 and 29 and start your car.

Gun66xml would your solution work if the Electric Throttle Control light went off in ly 2010 Chrysler 300?
