All injection cars should start themselves without any throttle.  Needing
throttle would indicate a fault, possibly with the cold start injector,
throttle sensor, or ignition.

Just get in to the car and turn the starter key till it fires. There is no need
to depress the accelerator pedal. The cold start mixture is automatically set
when engine is cold. Check the cold start injector circuitry if that fails to
get engine going satisfactorily.Usually the engine temp sensor for the ECU has
problems.
