You didn't tell us that in any of your previous posts did you! Probably the problem.

Change the fuel filter and use normal diesel and see if it's now ok

Even my TDi disco doesn't like cooking oil in this weather i'm on 100 diesel till it warms up a bit

fit a piece of clear pipe from the filter to the ip. if you see bubbles you have an air leak. one of the problems with using veg is it is thicker then derv so the pump has more trouble pulling it up from the tank, if you have any weak joints in the fuel system or blocked filters it will pull air in at the joints. also check the lift pump located under the exhaust manifold, if it has a screw in the centre take the cover off and clean the gauze filter inside.

I had all the above issues and it drove me round the bend, all sorted now and running better then ever on anything from 100% derv to 100% wvo (when not too cold)
