A quick look at the parts diagrams does not show a hand primer pump and there is not a lift pump in the fuel tank (edited - however, see later post since some do have an in tank pump). So it looks as if the filter/pump should be self priming. However, if there is any wear in the fuel pump (or an air leak in the piping) it may be a reason for it struggling. If possible, it may help if the filter could be filled with diesel - either by removing the top and pouring some in, or using a vacuum pump/syringe to suck some in through one of the connections - maybe the water drain to avoid disturbing the top again but this would leave the filter still full of air.

Odd if you don't have one.   Our 2002 90bhp Xsara has one.   I don't have a picture of it but this is the one on my C5.

The parts diagrams for the 90 hp 2.0 hdi only shows the priming pump with a Siemens filter and not with the Bosch one. For the 110  hp 2.0 hdi it only shows Bosch and Mahle filters, both without a priming pump. But another look at the fuel tank level gauge shows some of them have an electric priming/lift pump as part of the level gauge and some do not - to see which applies here the car vin would need to be used. Now if there should be a pump, I would have a look/listen to see if it is working and check the handbook for a possible fuse that may have blown. You can also check for a 12 volt supply at the in tank pump, I think by lifting the back seat base and removing a rubber cover to see the top of the level gauge. There was recently somebody on here whose in tank pump had failed on a Xsara Picasso so it is something that does happen. One of their checks may have been to see if fuel was pumped to the filter.

 

To check your own car parts diagrams you need to register on the service.citroen website, as another professional and a member of the CItroen Owners Club. The parts diagrams are free to see and the tank gauge/pump can be seen under Mechanical, Engine, Air and fuel supply, Fuel tank fuel gauge.

 

 

Depending on the above, this may also be worth a try, from the Citroen manual, but it may give a fault code although it does not mention it -

 

4. Injection system BOSCH

4.1. Checking the pressure sensor on the fuel high pressure common injection rail, DW10/DW12 engines (absence of engine starting)

Disconnect the connector of the fuel high pressure sensor (located under the fuel high pressure injection rail).

Operate the starter :

• The engine starts : Replace the fuel high pressure sensor
• The engine will not start : Continue the checking
