With 4 small jars you can lift the fuel rail and crank to check fuel delivery.

Also I'd say remove the fuel pressure regulator and check its gauze's are not completely blocked.

Hoggys spark check is worth doing any neighbour you could borrow to crank while you can look at the plug?

Where are you based maybe a forum member is local to help

or a test you may be able to set up with cable ties in some form to hold some thick cable on the exposed plug thread and connect to ground and then try in the dark so you can look for the spark from the drivers seat looking through the windscreen

With cable you should be able to position the plug to be in line of sight

Looks like left hand drive so ignition switch means sitting inside I guess.
