Hi and thanks for using 2CarPros.
If you have spark and fuel, it should run. Now, I can't see the tachometer when cranking, so make sure it is moving a bit. Next, and to be honest, it doesn't sound like the timing is right. The times it sounds like it's trying to start doesn't sound like ignition to me, but rather low compression in one of the cylinders.
With that in mind, I suggest doing a compression test. Here is a link that shows in general how compression is tested:

Here are the specs and specifics to your vehicle for testing compression. You can't do it at normal operating temperature, but do it as is.
Check compression with engine at normal operating temperature and throttle in wide open position. Prior to performing test, disable ignition and fuel injection to prevent fuel from being sprayed into cylinders while cranking engine. Ensure is fully charged and that cranking speed is 250 RPM. Standard reading should be 135-184 psi. The maximum variation between cylinders is 28 psi.
Also, make sure the distributor is correctly installed and the firing order is correct. See picture 1 for firing order. On the distributor, make sure the plug wires correlate with the correct positions as well as the plugs.
Let me know what you find or if you have other questions.
Joe
