The vehicle has a new starter, new battery, new fuse block, new ignition switch, electronics work, radio, speakers, lights, windows, back trunk. Car will still not start

Car was working fine during test drive and 3 days after taking it home, all of a sudden, no crank no start.

Hi,

The starter engages when the starter relay primary side is energized by the powertrain control module. Once the primary engages, power from the starter fuse (40 amp / under-hood fuse box) is sent to the starter solenoid via a purple wire at the starter motor.

I'm not sure what all you have checked, so I'm going to start simple. Have you checked the starter fuse and starter relay? If so, have you tried starting it in neutral?

Let me know what tests have been done on the wiring so far. I attached the starter circuit wiring schematic below so that you would have a reference. Actually, we both can use it. LOL

Let me know.

See pic below. Note: I cut the pic in half to make it readable. I did overlap the two so you can follow from one to the next.
