They don't always. That is were the skill comes in interpreting them.

did you replace the the lift pump or the high pressure pump ?

The one inline under the passenger rear floor

Has any one even got a clue cos I haven't

My money's on the high pressure pump.

Sounds like the same issue you had 2 1/2yrs ago. What did you do then?

Rob, are you stating its under the bonnet, or are you asking if its under the bonnet? I truly hope you are stating,!!

Sorry for sounding a divvy , I presume its the pump under the bonnet ,an expensive item to change if its not the problem

I think so, i'm not a Diesel buff, but usually there is a lifter pump or low pressure pump supplying the injector pump, or rail in common rail which i think you have, if it runs ok at first then wont start, i would steer towards low pressure pump, but im no expert. Good luck

Starts great when cold or if car has been left for up to half an hour, any more and you have to wait for it to cool down again, I'm stuck

It's not primer pump ,it happened once and I changed the primer pump, it still would not start till it cooled down

It's a common rail diesel, there are two pumps, a lift pump and a high pressure one. I believe the HP pump is under the car. There is no FIP. The HP pump is known to fail.
