Hello, it sounds like you have low battery and system electrical voltage which is preventing not only starting the vehicle but also maintaining enough power to operate the vehicle's components as needed. Start by charging the battery and having it tested to ensure it is capable of sustaining a load and powering the vehicle. Then, once you have a solid battery (which will initially likely resolve all the concerns you've spoken of...once trouble codes are cleared), you'll need to have the charging system tested to find out if there are problems there too.
