Sorry I should do a bit more investigation before asking.
Car would not start today after a month of not being driven.

Battery was disconnected and was fine, I checked the voltage.

Its turning over fine, and seems to start catching on a few cylinders for a second or two but that's about it, then it stops.

Here is a quick vid on the 5th or 6th attempt to start. I'm curious what you think it could be.

Usually I hear a sucking type sound from the pump when the key goes to position 1. I think its not doing that sound any more.

I'll read through the Elsa manual how to test the pump properly. Pump fuse is ok, and all the other fuses are intact too.

I already have the VDO pump, but I didn't buy the seals. I'm going to order those too now.
