I recently changed my valve cover gaskets on my 2011 Lexus ES350, in doing so i had to disconnect the battery and I stupidly disconnected to ecu to get more space, now that everything is put together i cannot start the car unless i hold the start button for 15 second, even then the windows, navigation, wipers, etc. won’t work, when i press the brake and click start it does nothing, and in accessory mode a bunch of dash light are on, can anybody help?
