our newly acquired 190e wont start!!! when i jump the starter solenoid to the battery with the ignition switch on the engine starts right up. i just cant do this with the key... seems as if the problem must be in the start switch, trans interlock switch or wire harness. surely there are some points to test these switches. your help greatly appreciated. my wife loves driving this car after driving a ford f150 for the last 17 years, so she wants this "new to her " car fixed.
