2013 Focus. Car has been running fine. Parked, went into a store, came back out and car wouldn't start. Shut off lights and radio and got it started. Drove 5 min home ,parked and shut it off. Won't start. I have lights, interior lights,radio and I can hear the fuel pump start when I turn the key. The car is serviced regularly and about 6 months ago the dealer reflashed the TCM .If I go to system check on the dashboard menu, it says all systems normal. Any help would be appreciated. Thanks.
