Re: problem of fuel supply
Fabien,
First check that there is no airlock in the system. I don't know the Renault, but on my Yanmar I can use a lever under my mechanical fuel lift pump to push diesel to the injector pump with the bleed screw open. Sometimes it takes several minutes to get all the air out of the line. Once you are sure there is no air at the injection pump, loosen the fuel line connection at the injector and turn the engine over until you are sure there is no air coming through and then tighten the connection. Repeat for each injector, if more than one. Then try starting the engine. If it doesn't start, you may have a problem with injection pump or the injector itself. Either get a mechanic or take the pump and injector(s) off yourself and take them to a diesel injection repair specialist (check the Yellow Pages under "Engines-Diesel"). If you remove the injector pump yourself, be aware that it has to go back in exactly the same way and may have to be "timed", as it is syncronized to the camshaft. If you are not mechanical leave removing and reinstalling the pump to a pro. Bonne chance!
