Hi I'm after some advice

I have a starting problem with my 2002 406 90 hdi.

The problem is this. It starts fine in the morning, when you turn it off when its warm it will start up straight away but if you were to leave it for 10 mins or so it then has a very long crank time before it even entertains the thought of starting. once started it runs fine. Any ideas??

It has been sugested that I should change the leak off pipes on the injectors as they may be perished and when warm could be letting air into the fuel system. does this sound likley

thanks in advance for your help

If the leak off pipes were perished and letting air in, they would be spewing diesel out as well.

Somebody else recently had a similar problem on this forum, it was cured by a new fuel pressure regulating valve which is fitted to the back of the (Bosch) high pressure pump. The ECU will not fire the injectors until the minimum pressure is reached.
