From what you have described i am more inclined to say its a fuelling issue.
Firstly by opening the diesel line you have allowed air into the fuel system. the car will not start now as the fuel lines need to be primed. Try turning the ignition on to the second point for 5 seconds and off several times and then see if that starts it. If not you will need to remove the diesel filter fill it with diesel and then prime the whole system manually by puchasing a hand pump usually readily available from a parts store, about ten pounds or so, and bleed it that way. (check mondeo forums for more in depth instructions as this is a novice mistake and happens all the time with them)
Now down to the main fault, dont go on your mates advice! These cars run on very high fuel pressure usually between three and five bar, just opening the fuel line will only show if theres fuel there, not what pressure its under. when you first start the car modern engines automatically prime the system to the correct pressure, but if its not getting enough fuel the pressure will eventually dip too low for the car to function and eventually stop. Two to three miles is about all you would get from a faulty pump.
Get it running and get it pressure tested first. If it does come back with low fuel pressure you will be looking to replace the fuel pump sender within the tank. Also the bracket which secures the holder to the base of the tank only has a small opening in it to allow fuel through to the pick up and this could have became blocked with deposits or sh*t which you always find on base of the tank.
My gut instinct is that £68 worth of diesel means it must have been rather low on fuel and filling it could have easily dislodged deposits on base of the tank.
If it does say its low pressure i would strongly advise you to seek a garage to do the work as working with fuel is highly dangerous and you have a full tank of it that will need to be removed. If however you choose to do the work yourself then leave another comment and i will send instructions to how i would do it.
