I have a 52 plate petrol Renault Laguna 2 1.8 auto sport tourer with 65k on the clock over the last fews months I have had real problems starting the car when the engine has reached its correct operating tempreture. The fault is intermittant. I can run around all day in it with no problems and them leave it for 5 minutes and the thing wont start. The engine turns over fine but never fires. To get around the fault I lift the bonnet and let the engine cool. No warning lights come on the dash and the water temp gauge shows normal. People have suggested a fuel issue and I intend to replace the fuel filter first, if I could find it. Having looked in my Haynes manual it doesnt state where it is, so if anybody knows please let me know. Plan B is to replace the fuel pump and sender unit located in the fuel tank. I would be grateful to hear from anyone who have suffered from this and would love to know where the fuel filter is located. I don't fancy paying £69 to have a £6 filter changed.
