Bought my xantia 1.9td in November. When i went to pick it up it ran o.k. It has been stood since then un-used and when i tried it yesterday the battery was flat so we towed it and it started first time. Left it running for a couple of hours but when i tried it this morning the engine turns but wont fire. Heater plugs were changed when i bought it. The only other problem i know about is that there is a wire that comes from the second injector that goes to the loom , it has a pink,green and brown wire in it (the brown one has snapped.(what is this for?). Also , should the rubber fuel primer bubble be hard all of the time because when the engine has not run for a couple of hours it becomes soft?.
