Wondering if anyone else has had this problem. I am thinking it is a grounding issue on the ground side from the negative terminal of the battery to the starter solenoid.
With battery normally connected, the car won't turn over, just the starter solenoid clicking, trying to get enough power to turn over. If I try to jump the car with the leads on the positive and negative terminals of the battery, the same thing happens. If I run the positive lead to the battery and the negative lead to the engine removal mount with jumpers, the car starts perfectly fine with no hesitation.
I have a brand new battery, brand new starter, and brand new alternator, as well as a brand new cable from the frame to the negative post of the battery as of today. All multimeter numbers from the above locations read fine if not a bit low but still more than enough to crank the engine.
I can only think that it is a cable in the harness from the starter/alternator, to the battery. Every connection is tight with no rust as I just cleaned al connections today and during installation of components. I don't remember a ground cable from the alternator to the frame of the car, is there supposed to be one? I just thought of that. Would that cause the problem?
I am out of ideas and will bring it to the shop tomorrow if I can't figure it out. I am just seeing if someone had this happen to them and if they had a solution.
Also, I swapped the starter 3 days ago and it turns just fine for two days before this occurred.

Disregard. It was the motor mount from the mount that holds the alternator to the engine ground. I thought it was a ground. It just wasn't snug.
Thanks for the help.
