Hi there.That loud noise could have been made by several things; the fact that the engine doesn't start points to one or more of the timing components as being the culprit. To find out, either perform a compression test (no or very low compression means engine damage), or remove the valve or timing cover to visually inspect the condition of the timing components.Please let me know if you have any other questions.Best Regards.
