It wasn't until later, after my uncle told me there was a battery charger in the shed, that I remembered what I know. After several tries at starting, with a revitalized battery, decided to take the fuel line off and see if the injectors were actually injecting petrol... they weren't. SO, I guess 2 liters isn't enough fuel to run the car on, I will have to remember that for when I do my long journeys... no going below a gallon left!
Tomorrow I will get to the petrol station, get a further 5 liters, and try again.
I am glad I'm finally getting on top of when something like emotions are stopping me from thinking things through correctly. There's a long way to go yet, I need to make it a couple of minutes, rather than a couple of hours... but still, it's an improvement over what it was! :-D
