Re: hard or no start

Use a timing light to see if its getting spark when in crank position (key switch).

If no, disconnect kill wire, black/yellow , and see if spark returns.

If no, disconnect main harness and jump the starter to crank it and see if spark returns.

If yes, keyswitch is probably worn out.

Ignition switches are a common wear item.
