My truck wont start. I thought it was the battery and changed it. i go to turn the key and id doesnt even click i wasthinking maybe the starter

Hit the the bottom of the starter motor with a hammer while someone is holding the switch in the crank psition.If it cranks then you need a starter.Also you can check with a test light or meter and see if thereis voltage at the starter solenoid.The big wire shold always have voltage and the small wire should only have voltage when the switch is in the crank position.Good luck.
