Issues starting
 

hey guys really need some help, i have a 2002 chevy avalanche 1500 Z71 5.3l and it wont start. everytime i turn the key nothing happens, its not a battery the battery is charged and the alternator is fine, its not getting any power at all and after wiggling the wheel and key this morning it started but now it wont do anything. any thoughts? could it be the ignition maybe?
