Get guys I just bought a 2002 lexus is300 and in having issues with it when I try to start the car none of the lights come on, on the dash but the lights in the car like the dome light works and when I try to start it it clicked once but that's it I had replaced the alternator, the radiator, the starter relay, and starter and its still not working. Please help me

 

Did you have the battery tested?

don't see battery in your list - that should have been first.

Wondering about the radiator, I hope you didn't replace that to troubleshoot the issue

 

Check the fuse.
