Do not use ether. with a turbo diesel it can cause more problems.
is it getting fuel? thats a cheap way to trouble shoot. remove an injector line and crank it over, fuel should shoot out. if not replace your filter. if it's not that then test your glow plugs.
good luck, tim

Have you try to spray ether on the intake to see if it will cranck, if it does, then you can troubleshoot the glow plugs

If the engine turns over like normal, the starter and battery are working.
I don't know how many times I had someone ask for a jump start when the engine was cranking over just fine!
The glow plug harness may or may not be bad.
But to say that is the problem without more testing and info supplied is not in any way a professional diagnosis or a reliable lead to the solution.
You might have one or more bad glow plugs, a bad glow plug controller (not cycling or cycling for too short a time for the outside temp), a loose connection at either, a loose or bad ground, or (least likely) a broken wire in the harness (AKA a bad glow plug harness).
I found this looking for the test procedure for the glow plug system as it has been almost 20 years since I had to test one, and my 1991 7.3 is having issues with it cycling for too short a time for how cold it is out side.
