Tried everything I can think of, but still no spark

I'm not after advice for rekindling a marriage (right now), just want to get my T25 back on the road.

I'm at the very modest limits of my knowledge, but can't for the life of me work out why the bloody thing won't start. 

We've changed the ignition module, the coil, the distributor and cap, leads and spark plugs and tried with a variety of old and new kit, testing at every point. The battery is good. There is fuel in the tank. There is power tested through to the distributor. The old and new dizzies spin when the key is turned. But still no spark. 

We're going round and round in circles with it so thought I'd try here in case someone has had a similar issue in the past and I've overlooked something straightforward, which is very likely. 

In the video here - https://i.imgur.com/6idwTdI.mp4 -  you can see and hear that the willpower seems to be there for it to start, so the lack of spark is doubly annoying. 

Photos show the engine set-up. It's a 1985 petrol 1.9. Thanks for reading and any help you may have to offer  :D

I see no earth lead from the top of the LHS head to the body under the coil ……

Have you confirmed spark from the king lead. 

If you have no spark from the king lead, remove the coil wire that goes to the module and ground the coil negative a few times to see if you have spark. if there is no spark its coil,power to coil or the kinglead.

Report back.

It might be worth looking at the troubleshooting procedures in the workshop manual.

Is that a new aftermarket distributor?

Did the engine just stop running ?

Have you got 12v live to the distributor and earth to it to as well as both tom the module
