I have looked through previous threads for non starting but still have problems. Van is a 2.4 non turbo diesel. Last out for a run about 2 weeks ago - did start but with minor delay, plenty of fuel, starter motor turns over well ( has had to be recharges due to my attemps at starting). Fitted new fuel filter after trying for a few days of non starting. Found 12v on isolater valve on diesel pump and could hear a 'click' when tapped it with a 12v lead. There is no white smoke after trying, maybe there was initially but not in any quantity. Anybody got any ideas please
