LX 485 Starting issue

[tcu101]

Just purchased a LX 485 a couple months ago Used it for 10-15 hours and had no problems. But just recently im having starting issues. I turn the key and it will make a clicking sound from fuse box and will not start or turn over. If you continue to turn key on and off and get lucky it will finally start. I just replaced ignition switch and starter relay. cleaned and tighten battery cables and terminals. Thoughts?

Starter interlock relay will do that, clean all grounds also and make sure the cables at the battery are good. They can be clean and still be bad under the insulation.

Thank u for your help and time! Should I consider replacing the cables from the battery?
