Hi since owning my XJ-SC some 20 years now I’ve always had a problem with hot starting and this can be very embarrassing if your in a concours event and the judge asks you to start up i have always had the car serviced and my last was in June this year when i also had a new clutch fitted

The problem i have is from cold the car starts instantly and will start ok after a few minuits if left for say a hour or so it appears to take for ever to fire ive mentioned it lots of times but no one can ever find the problem The car as had new Battery new pressure valve new filters slosh tank cleaned new pump new temp sensor new plugs but still it does it To me it seems as if the fuel in the pressure rail evaperates I was wondering if any of you had had a simular problem im sure it can only be something simple

Any Ideas Folks

  I have managed to find on ebay a ECU same as the one fitted to my car that’s supposedly in good working order so I’m going to see if this cures my hot start problem fingers crossed

  Unfortunately its not cured my problem The car will start ok when its hot but seems to take longer than it should when firing but I will just manage until I think of something else to try
