Why won’t my car crank?

Hello, if your vehicle will not crank, and your battery is known to be good and fully charged, you will first want to check the battery cables to ensure they are securely attached and free of corrosion. You said your radio will not turn on but your battery is good? Are there blown fuses from a poor or reversed vehicle jump start? Something is missing here from the information. It's impossible to know what without hands on testing. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
