I have a 2009 Nissan Cube and when I try to start it you can tell it is trying to start but nothing. I even had it jumped just in case and still it wouldn't start any Ideas?

When you jump a car, you sometimes have to let the other car charge your battery for 5-15 minutes, in the case that a dead cell in your battery is dragging power from the system(s). Try charging the battery with another car, then try the jump again. if still no, you have 2 main alternatives- get your battery checked and get your alternator checked. There are other issues that can cause this type of non-starting situation, but a dead cell in the battery dragging down system power or a bad alternator, leading to an extremely dead battery would be your 2 leading causes. Other possibilities are simple, like spark pulgs/wires, to huge, like a broken timing belt/chain
