first connect her to a well-charged car battery. if she doesn't resist to start then, you should buy a new battery!
check also wether the cables are properly connected to the battery.
if the battery is not the problem you should check every part of the ignition system, starting from the spark-plug and ending with the cdi-unit. measure the resistance of the parts and compare them to the nominal values.
good luck and let us know!
