Hi
Had the same problem on my 2ltr diesel mondeo turned out to be a couple of faulty fuel injectors.

You likely got a load of water contaminated fuel, diesel fuel absorbs water like a sponge. Drain the fuel or add a water absorbing diesel fuel additive available from many parts stores.

indicates that the fuel was petrol and not diesel
best id to drain the tank , change the fuel filters and refill with the correct fuel
could be contaminated tank at the station but as most have a petrol and diesel hoses side by side it is easy to fill from the wrong hose

on a ford mondeo 08 the fuel filter is at the rear of car u take old filter put in new one fill with fuel put back together then put a pipe on feed [there might be a bleed niple on top that will be easier] suck till fuel comes out conect pipe back turn ignition on for 15 seconds 3 times to clear air then start done

You will find the diesel pump at the petrol station have slim nozzles that release the safety feature and the other petrol types a wider nozzle thus preventing you from putting the incorrect fuel in your tank. Your spare tyre compartment should contain a special funnel to use that releases the safety catch for you to fill from a can.

No, the injection pump is the fuel mover. There should be a means to manualy prime the system. Look for a hand pump with a knob . Unscrew the nob and pump it up until iy pressurizes. The lock the pump dow and hit the key. Good Luck

I had a similar problem in my Mondeo 1.8 TD a few years ago and this was cured by changing the engine oil and filter to the correct type.

I had used the special Duckhams 10w-40w Turbo Diesel (or was it 15w-40w?)  oil but once I changed it to the correct Ford 5w-30w (Formula-E ) ordinary oil, the turbo worked a treat every time.( I understand now that there is an even "thinner" option that works even better so worth checking ....Something like a 1w-30w )

A strange answer I know, but true

The only reason I used the Duckhams was because the chap in Halfords said it was the best one for a Turbo Diesel
