I am satisfied that the problem is not glow plugs.

Let's work on fuel.

Temporarily remove the hose from the input side of the prefilter. Let the prefilter drain into a small container. Check the drained fuel for debris or water. Reconnect the prefilter. Tighten all fuel line clamps on that line (4). Give it about 25 hard strokes of the primer pump. You should see fuel bubbling in he prefilter in time with your pump strokes. Does the primer pump leak fuel? (If so, it also sucks air.)

Move to the canister fuel filter. Open the drain plug and let it drain a few ounces into a small contaner. Check for debris or water. Secure the drain plug. Crack open the vent on the top of the canister. Put a towel over it. Pump the hell out of the primer pump until fuel is squirting out of the vent. Secure the vent while pumping. Continue pumping with very brisk strokes for, say 50 strokes or so.

Now try to start it. It may help to jump it with a second battery as the cars battery may be a bit drained from all the previous cranking. Does it sound like it's turning over fast enough?

Please try those steps and report back.

Do I see a valve cover bolt loose in one of those pictures?
