I cranked my motor up and it was running then it started making a funny sound so i cut it off and tried to crank it up again and it would never crank. What would be the main reason for it not cranking?
If the engine cranks (turns over with the starter) but doesn't run (engine stops turning when the starter stops) It's usually one of three problems:
It sounds like yours may be mechanical based on the noise prior to you turning off the engine.
This answer is based entirely on the assumption that you have a gasoline engine and not a diesel. It would help if you would edit your answer to include make model year and engine size.
