Answer
Bob,
The oxygen sensor, fuel, etc. only come into play once the engine is cranking and/or running. Your problem is more basic in nature. If you're sure the battery is good then the problem is in the cables or starter. If the cables and connections are good, and the clicking you hear is coming from the starter,try tapping on the starter with a hammer while someone is holding the key in the cranking position. If the starter then starts to operate, it's bad and needs to be replaced ASAP. If the tapping doesn't get you anywhere, you'll be needing a starter.
