I will listen to the video again when I am in a quieter place, but it doesn't sound like the engine is turning over. That tells me it is probably a problem with the battery (best case scenario), or the starter motor.
My first 2 checks would be:
Get the battery tested at an auto parts store
Try jumping the bike using a car battery. Car red (+) terminal to ...
I've had this exact problem on my 2001 325i a few times and I learned from a friend what it is. When you run that engine for just a few seconds it doesn't actually get the cylinder or cylinder walls warm, combined with an engine running rich (since it's cold) you get lots of non-vaporized gas in the cylinder. Then when you try to start later it is flooded. ...
The most probable reason for the engine not to start after a coolant loss is a compression loss due to overheating. High temperature causes a (usually) aluminium cylinder head to bend and lose a good airtight contact with an engine block.
I'd start with a compression check, it won't cost you much.
Because the motor fires and runs briefly using starting fluid, the starting and ignition systems can be presumed to be OK.
The truck's problem is fuel flow. You've shown there's fuel at the fuel filter, but you need to go farther and check beyond the fuel filter. Somewhere between the fuel filter and the cylinders themselves fuel isn't flowing.
I don't ...
