Car sat for 14 days. Will jump it and let it run but if it sits for 4 or more hours without running, it won't start again.
My car has an automatic transmission.
From what you've described, it sounds like your battery is not capable to hold a charge anymore for long periods of time. I suggest having the battery and charging system checked. Have a certified technician, like one from YourMechanic, diagnose the battery firsthand and help you fix it accordingly.
