When you try to start, that sounds like a weak battery to me. The battery appears to take a charge (shows good volts) and may power some accessories but cannot maintain the current flow required to turn the engine over.
When we charge the battery it won’t start. Left it for a while and still wont turn on. Plus that wouldn’t explain the P0021 code.
