Make sure you're using a lens that worked before on this camera.. many consumer bodies lack the built in focus motor, so you must purchase lenses that have the motor built into the lens. If it lacks a motor - no auto focus will be possible.
Remove and re-seat the lens.
Make sure that any Aperture ring on the lens barrel is set to the smallest (largest number f22) possible.
Make sure any and all Auto / Manual Focus switches are set to A or Auto.
Try taking a picture in broad daylight - or other well lit area - if the subject is very dark, the auto focus will struggle or "hunt".
Let me know if these suggestions solve your problem - good luck!
