Won't start when you turn the key it doesn't turn over but the dash lights and radio come on. we charged the battery and had the battery checked. do you think it could be the starter?

On rare occasions, the neutral safety switch can fail, or the clutch switch if this is a stick. It could also be a broken wire at the starter. But more likely the starter, especially if there is a lot of miles on the vehicle. There is a two-person check you can do with the starter. You will need to locate the starter, then one person holds the key in the "start" position while the other raps the starter from below with a heavy object like a hammer. Most often the starter will respond to this therapy in just a few strokes. If so, replace the starter, the brushes and commutators are badly worn.

If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!

The starter is a very possible problem. also i would check the starter relay first by swapping it with an identical relay before spending $100+ on a starter.
