    Any Idea why my vehicle wont start after i replaced dead battery with brand new 12V battery? the dashboard comes on but doesnt start. I had this issue before like not starting from first time but now doesnt want to start at all like not reading FOB keys or need to be reprogrammed ? or something wrong with fuse or relay ? Any idea or thoughts ... thanks

    You could hold the fob up to the button per the owners manual. It will work without a good fob battery in that manner. Otherwise measure your 12v. A new battery should be 12v or better.

    If someone played with the orange hv battery disconnect it may not be properly engaged with the last side push.

    If there was a reversed polarity jump start attempt, things could be serious.
