Stuck 'To Do' note.

[Viking]

Spoiler below!

Sorry I can't remember the order. From what I remember I got to the excavator first of all and plugged in the cable. 2nd thing I did I managed to get the key and stuck it in the control panel. Maybe I am being silly but were the key and gasoline in the same room? If so then I only picked up one and came all the way back to pick up the gasoline. Afterwards, I found the petrol and took it back to use.
