Welcome to the forum, If the starter won't crank, make sure the battery connections are good. Then check the circuits at the starter relay in power distribution center under the hood. Voltage for the load side of relay is hot all the time. Voltage for the coil side of relay goes hot with the key in the crank position. You can unplug relay and use a testlite on the circuits.

Why did you buy a new battery? There's a dozen different symptoms that owners describe as " won't start". If you describe what it's doing, we can give you a better idea of what to check.
Does the engine crank normally but it doesn't run? Do you just hear one kind of loud clunk from the starter but it doesn't spin the engine? Do the headlights or dome lights go very dim or stay bright when trying to crank the engine? Did the engine stall previously while you were driving the car, and it wouldn't restart, or was it running fine the last time you drove it, and now it won't start after turning the engine off?
You can't just tell your doctor you're in pain and expect him to treat you without giving him more information. He won't know if you have a stomach ache, a hang nail, or you cut your foot off with a chain saw!
What have you done so far to try to diagnose the problem?
