Hi and welcome. You would need to check to see if you are getting if you are getting 12v to the small terminal on the starter when trying to turn over the car.If you are not getting power it is not the starter if you do get 12v then then it is the starter.I am not sure what noise is about the only this on the passengers side that wouldnt make the car not start is the computer. let me know how you make out.
the relays could be other systems . the starter relay is located on the drivers side. under the panel.if the relay is not activating when you turn the key when in start position then it is probably the ignition switch which are common.
12 v to small terminal large terminal should have 12v already.
