Reasons my 2013 nissan altima wont start just clicking

Seized engine, bad new starter, major voltage drop.

Make sure the batt terminals are tight , things should be tested before you spend money on parts you don't need , you could have bought test equipment instead ., it's not rocket science , we can help . Did you replace those parts , who works on your car ?

I agree, sounds like a bad battery cable connection. Check the connections at both ends of both cables. You might have a bad connection where the negative battery cable bolts to the engine or the frame. Especially if you notice the area is a bit rusty. Hope that helps! Jim
