My 2007 Dts was just on I parked it then tried to crank it it only makes 1 click by fuse box but want turn over

Hello, 11.8 volts isn't enough to start any car. You need 12.5 - or more. That said, it's impossible to know what's going on without hands on testing and assessment of the concern. Cutting corners and trying to get it to run isn't a good idea; hands on evaluation by a professional seems like the most reasonable choice. Sounds like other issues such as related to the motor mounts and "transmission line" could also influence the issue, so definitely - seek professional guidance.
