Greetings peeps. Just want to see if any one has any ideas before i start. Disco 2 TD5 Auto cutting out and air in the fuel system.When it cuts out it is a git to start. Items already replaced are
1. FPR and gasket
2. In tank fuel pump
3. Fuel filter
4. Repaired fuel line
5. Injector Harness
6. Injector copper washers and seals.

Anyone got any ideas where to look next?

How far are you getting before it cuts out?

Managed 2 miles today mate, yet when i get it started will idle quite happily

Are you able to get a pressure guage on the Fuel Regulator? Was the new fuel pump OEM or aftermarket?

OEM for the FPR and the fuel pump.

Check the air bleed valve(s) in the fuel filter housing. I "lost" the membrane type cap on mine and had to wait for the air to be purged every time I tried starting. Take a look here, great diagram towards bottom of first page

thanks for the link and the info. will give it a good dose of looking at 1st thing saturday

Did the copper washers show signs of carbon deposits on the face or were they all clear? Did you clean the injector ports up before re-fitting the injectors?

previous copper washers totally knackered. New washers totally fine. All ports cleaned prior to fitting. On turning over by hand after washers previously replaced compression was a lot better.

what was the repair to the fuel line?

it was a knackered connector at the fuel filter.Thinking the problem may be around the fuel filter area.

did you replace the connector or repair it?

You could be right. It could be a cracked filter housing or a knackered/missing bleed valve.

cheers for the info ratty will start there 2morrow morning and hope. The connector was replaced

Well replaced fuel filter and air bleed valve, removed fuel pump and cleaned filters, cleaned all fuel filter connectors and fault is still there. Have noticed however the the no return valve on the fuel filter is not there but it was only fitted on certain models. The pump will complete the purge cycle but if the ignition is then switched off you can here the fuel flowing back into the tank so I think that it might be the valve in the fuel pump. Any other ideas gratefully welcomed.
