There may be fuel in the filter but is it and all the pipework full? A lift pump with a duff valve will allow the fuel to run back overnight but will be fine for the rest of the day after the 1st start. Your symptoms are exactly the same as I once had. A new lift pump cured it. Failing that you have a air leak in the fuel system. Quote Link to comment Share on other sites More sharing options...
