Recently I was unable to start my car. All the lights turn on but when I turn the key nothing happens. No crank , makes a rapid clicking sound then hums as I hold the key turned. Only on rolling push starts the car turns on.

I came across this issue in the past and it ended up being a fuse.

I just changed the battery , fuses , and relays.
still no start.

Any ideas before I try changing out the alternator or starter?

 

i dont have an X. on my IX i can tap 12v to relay piug #5 to spin the starter

 

Sounds like your starter might be failing. Can you verify it is working correctly?

 

Rapid clicking noise can be due to low battery voltage. Did you double check if the cables are tight on the battery?
