I have a 2003 Toyota Prius. It has been in good running condition up until now. The issue is that it sat for a week and a half with no use and now when I wanted to start it up, no lights on the dash come on and it makes a weird whirring sound when the key is turned. When I try and turn it over, there is a click and that whirring sound, but that is all. I tried jump starting the car but that did not start the Prius (i.e. Did not solve my problem). Can someone please shed some light on what my problem might be?
