Engine Starts then wont start
2007 Compass will start sometimes and not start others, replaced battery and battery terminal, had towed to dealer twice but it always starts up for them and since the service light never comes on( even when it wont start), they say they cant diagnose it(they keep it all day and of course it starts for them). When it wont start all electric seems fine(no dimming) but when you turn the key, nothing(all electrical stays on), but no clicking or anything. Of course it's out of warrenty. Any suggestions, this towing every couple of days is aggrevating.
