82 C10 won't start

82 C10 won't start. Has lights, radio and dash instruments, started once after charged battery. Wouldn't start after that, took battery in and had it checked, was ok and charged up, tried again and nothing new. Tried jumping it, nothing. Any thoughts?

Do you have spark and fuel?

Figured it out, the starter was bad. Thanks Heavy Chevy for the reply. :)
