Transit Connect Faulty Injectors & Fuel pump
FORD TRANSIT CONNECT (P65_, P70_, P80_)

If they done there diagnosis right then the injector’s should not have been removed/replaced. They should of carried out a data check on the fuel pump pressure and fuel line pressure to see if they are the same as the recommendation supplied on the data list, then would be able to see if that is within tolerance. If all good then a fuel simple is very easy to do to see if is has water in the fuel (can see it floating on top) , if that is good then removing the fuel filter and check for metal fillings in the filter housing, ( the data list can sometimes find that the pump if failing or breaking up when checking the data list when the van is under load/boost and will see the pressure drop off). Then a leak test on the injector’s to see how they are proforming. But to remove the injector’s, get them tested and to say it’s the fuel pump is very bad service as every step should have been checked over before the injector’s. For all 4 injections to be faulty is super rare.. I believe that they never checked it over properly. 

Metal particles in the injectors could appear only from the fuel tank, perhaps the pump itself at the gas station has some kind of output and thus the particles got into the fuel during refuelling and then into the tank, or the fuel was stored in some kind of dirty containers.

I’ve got exactly the same problem..what was it in the end
