What would be helpful is not posting statements like this: "...not start the car". No one can help with that. TELL US: Does the starter engage or not? Does it engage a few times then you get nothing? If it engages, is the engine turning over r e a l l y slowly? And "wont go into gear": If an automatic won't go into gear, I'd bet the Traction Control Relay is not engaging, but that won't cause the engine to not start.

Its starting to sound like a battery with a shorted/open cell or low terminal voltage, but again, you are not telling us enough to even guess.
