The pump in the tank isn’t a lift pump. The high pressure pump on the cam shaft has to suck fuel from the tank through the filter then pump it into the rail. Check that the system is bled properly. Next would be the drive from the camshaft to the hp pump. It has been known to break.

Got to agree - first port of call is air in the system, cannot be bled by cranking. If you just change the filter and the rest of the system is still filled you can get away with filling the fuel filter first and just cranking. If there is air in the low pressure side it must be bled using a pump (bulb type?).

The high pressure pumps don't usually fail - the end of the camshaft shears off, not always, just usually.

The HP pump is a red herring.

My son ran low on fuel last night and the car stopped. We put in some more fuel but it would only turn over and not fire. The RAC said that there was fuel going to the injectors but not very much. We continued to crank it over every half hour but no joy.

The bubbling sound from under the car is the in tank pump moving fuel from one side of the tank to the other and supplying the swirl pot that the main fuel line takes from and the return line goes to. That is all that this pump does.
