Clicking sounds like a bad relay or low voltage. Same with the glowplug relay.

I put a new glow plug relay in it and it's still making a whining sounds..idk about voltage it has all new battery cables and new batteries I've checked for loose connections but haven't found anything

Stick a volt meter on the big stud on the alternator. Have somebody crank the engine, look at volt meter while cranking. Tell us what the voltage reading is.

I got a battery load tester charging system is at 14.2 volts little over 12v while cranking

Are you getting white smoke out of the exhaust when cranking?

Any smoke?

There's no white smoke while cranking

You have to hook up a scanner that can read the sensor values and monitor the ICP or injection control pressure. It has to see 500 psi when cranking to fire injectors. You could pull the hex plug off the top of the reservoir just to be sure oil is getting to the HP pump you should be able to see it not too far from the top.
Also make sure the engine oil level is good that would cause it not to start as well.
Is the tach moving up a few hundred rpms when cranking?

A quality one which can pull the Ford Enhanced PIDs. The cheaper, lower end scan tools normally cannot do much on the 7.3L.

Bad glowplugs? Checked resistance in them today and got around 2.5 on all of them

If you aren't getting white smoke your injectors either aren't getting oil to them or they are bypassing all the oil that is getting to them.
