SPARK
FUEL
COMPRESSION
You need those three things. Isolate which one you do not have.
By "won't start" what do you mean? Cranks, but will not fire? Won't crank? Fires intermittently but won't stay running?

Similiar issue
Also have the same issue, turns over no start, new fuel pump and filter, distributor, plugs new gas. It sounds better than when I first got it trying to start, does make a new like gasping sound occasionally when trying to start.

If it won't run on starting fluid it's probably an ignition problem. Even engines with basically no compression will run on starting fluid.
I'd bet a lot of money that you screwed something up when replacing all that ignition stuff. Distributor in backwards, plug wires one-off, connector forgotten, etc, etc.

Ignition
But I didn’t replace anything on the ignition, checked grounding straps, good. Checked plug and firing sequence all good, just turns over and goes and goes, with some ether it gets excited like it wants to fire off and then goes back to trying to start.

Thought we were still talking about OP's truck.
Anyway, shoot it with starting fluid. That'll let you know if you've got a fuel issue.

Even when I spray ether in it it tries to start up and then goes back to cranking over and not firing up.
