I have a 2010 Focus SE couple - manual tran and I have trouble starting the car. I checked the starter, battery, alternator, fuses, key sensor and still the car will not crank. I tried to push start the car to check if it was an engine issue. The car ran/runs perfectly. I can not seem to figure out why the car will not crank over. I now have to manually start the car by connecting a cable from the starter to the positive from the battery. Please help.
