The car turns over, has spark and fuel flows......So why don't it start?.... I was driving and the car just stopped running, lights where still strong, battery good. It felt like it ran out of gas. No indication that anything was wrong. Thank You

Get a voltmeter and read the open battery voltage on the battery before you start it up-should be 12.4 volts or higher, less recharge battery. Now start it up and read battery voltage should be 13.5 - 15.5 volts with headlights and heater on. If not could be the alternator again not putting out or the battery is not taking the charge. Or the field generation from the computer
