when i try to plug my guitar into the amp it doesnt make any sound ive narrowed down that it is the plugin jack because if i twist and move the cable around it sometimes plays for a few seconds then moves and i lose it

i know its not the cable or amp cause i plugged another guitar into it if anyone can give me a little help it would be gratefully appreciated
