Can you be a little more specific. Are you saying starter doesn't engage at all, or does it crank but won't fire up?

You'll need to diagnose from the battery and cables, and move from there. As Stamp said theirs plenty of stickies and troubleshooting on line. You might try using a remote starter button across the solenoid on firewall after testing battery.

replace the ignition switch, rechecked key calibration to pcm, changed starter, and replaced the relays just for a measure, and still no turnover

Your throwing parts at it hoping for a fix. You might have to bite the bullet, and have a shop diagnose and fix problem. Time and sanity are more important sometimes.

Sounds like you replaced a lot of items might be time for a professional diagnosis. I had an issue where I turned the key and nothing, no clicks, no dimming lights, no indication just dead. Was Battery, replaced and fine, but that was my situation.

How many times in the past 4 years, it's been an alarm gone haywire, or a stereo or some dohicky, that an inexperienced shop or individual, tapped into a wire that they shouldn't have. Alarms, and ignition kills seem to be top of the heap! Oh well, without these wire tappers all we'd have is guys/girls that want to know why their 2018 GPS/ mileage/ water finding thingy went haywire, and should they bring it back to Ford! It always is 25-50 posts, to find out it was a connection, just like we suggested in the first 3 posts. Gotta love em don't yah!

Hate to ask, but did you check for voltage at the starter? There are 2 lines. One is a constant 12v for the starter itself, the other is a smaller gauge wire around 12, that's for the solenoid.
