Volkswagen Vento part and stands

Hello friends, my Volkswagen Vento 98 car starts and the engine stops, other times the engine does not start, it only turns, sparkle arrives in the spark plugs, fuel arrives at the injection ramp, the setting is fine, it reaches food to the coil, and I don't know what else to do, for your help thank you very much thank you very much
