There is a fuse on the right hand side of the HV battery pack but not something you should mess with unless you have proper safety equipment and training. Maybe there is another high voltage fuse somewhere if so that's beyond my knowledge.

Not sure about the latest version of Toyota's hybrid system but from what I know the engine won't start if the high voltage battery is not charged correctly or disconnected. My guess is there are a bunch of fault codes so the computer shuts off the engine to prevent you from driving the vehicle.
