I have a mercedes benz e350 coupe 2012 i put my key fob in to try and start it the dash lights up i can turn accesories on radio go through my dash options and everything tells me to take key out of ignition but when i go to turn it on does not crank or make any noise at all idicating that the engine will start ive tried taking negative terminal off the battery for about 20 mins put it back on and still nothing ive tried wiggling the steering wheel back and forth while trying to start it still nothing need suggestions on something else to try without dumping a butt load of money into it
