Okay, I got in my car leaving work going some where's all of a sudden my dash lights went off and the rest of my power failed it was if I had no battery it was at night the car then died I had to put it to where it could be figured out I then tried to start it it gave me a rapid clicking the sound you hear when the battery goes dead I then called someone they had my car towed and put a new battery in and said it was all good now I drove not far a again my battery ran down and I lost all power and it then died I had to push it again I again turn key to start I again get the rapid clicking so I figure the alternator is bad because it was not charging the battery so I get the alternator replaced and get a new battery and I go to start it and again only rapid clicking and when I go to start it on the dash the red battery is steady on and turn key and rapid clicking so I check all the fuses and they all checked out good so then I was told it's the starter so I get that off and it tested good so it gets back on turn key and again only rapid clicking I can't figure out as to why my car won't start please help me figure it out.

I have seen a bad positive battery cable cause this issue, it can look okay but be corroded internally. Also, it can be the alternator is still not charging even though you had it replaced, here is a guide to help test if the system is charging or not because it sounds like the battery is not being charged.

Also, make sure the DIM fuse in the rear fuse panel is okay, here is a guide to help and I have included the fuse locations as well in the images below.

Also, here is how to change out the starter motor ( under the intake manifold) and positive battery cable incase everything checked out. Check out the images (below). Please upload pictures or videos in your response of any problems so we can see what to help you with.
