SOURCE: Toyota Prius starting problem

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.

SOURCE: code P0A93 for toyota PRIUS WHAT IS THE PROBLEM ?

P0A93 is an inverter cooling problem. The inverter is cooled by a dedicated cooling system, which consists of an electric water pump, cooling fan, and radiator. This cooling system is independent of the engine cooling system.The mechanic should check if there is sufficient amount of coolant for the inverter, check if the coolant hose is not bent or clogged, if the water pump / cooling fan motor connections are ok, and of course if both of the cooling fan motors are OK
