There's a known problem with the early Toyota Prius (2001 - 2003), when running the engine for a long period of time without moving or when the car is driven only for short trips (short city driving), the Prius might not start.

You have to change the original battery with a 356 CCA which is bigger because the battery is bigger you also have to change what is holding it into place.

Check the heater plugs normaly when the engine is cold heater plugs work to heat up combustion chamber then starts easy,also long raning fuel filter mybe so change the fuel filter.
