Clutch replaced and now the car will not start

Replaced the clutch, when we tried to start the car it was registering no fuel. The car had a full tank as it was just filled up three days prior and not driven. We disconnected and reconnected the battery and the car started. The car will go into reverse, but struggles in first, and shuts off in second and third. Once the car shuts off in third it would not restart. Transmission? Wiring? Sensor? The car ran and drove fine prior to clutch replacement.
