Answer 1 - Vehicle Will Start When "Jumped"There could be several causes, but based on "...clicks once won't start starts when jumped.." suggests that there is something wrong within the cables or terminal clamps or connectors [corrosion inside that can't be observed] between the battery and solenoid, OR possibly a defective solenoid.
jump start the car and get a new battery and if it isn't the battery it could be the alternator or both, but try a new battery first
