I listened to it. It has little to no compression. I suspect the timing chain has jumped time. Now for the worse news. This is an interference engine. Basically, there isn't enough room between an open valve and the top of the piston if the timing is off. As a result, they hit and internal damage to the engine occurs. I believe that is the knock I heard when you first started cranking the engine.
If you want to confirm what I'm saying, first check the engine compression. Here is a link that explains how it's done. You will need a compression gauge, but most parts stores will lend one to you.
I have a feeling you will find three of the cylinders with little to no compression and one of them will have more. I'm basing that on how the engine sounds.
Try that test and let me know the results. Also, let me know if you are interested in removing the cylinder head and timing chain to confirm my suspicions
Also, if I am correct, the internal damage will have damaged several valves and possibly the cylinder head and piston tops.
Let me know.
