Primary fuel pump malfunction code after turbo replacement.

Hi,

I have just replaced the turbo (40k miles second hand one) on my 2001 ulysse 2.0jtd and after starting it and running briefly I stopped the engine and it seemed to continue to run on for a couple of seconds.

I checked the fault codes which were cleared previously and now P0230 fuel pump primary circuit malfunction is present and the engine light comes on if I leave engine running and then the engine cuts out.

The new turbo seems ok as it runs now without the blue smoke belching out, like it did with the old dead turbo! It was an awkward job changing the turbo !!!!

Does anyone have any ideas where to start ? Or is this likely to be a diesel specialist job?

Thanks in advance
