Renault Clio - Fuel System Problem

My 1996 renault clio 1.2 engine code d7f, (diet engine). wont start as it is overfueling? i have had an autoelectrician out to check my ecu and he tells me that i have a overfueling problem ,when trying to start the car ,the pressure in the fuel line builds up so much that it blows the fuel pipe off ,and the engine will only run for approx 1 second
hi thanks for the reply,i have just changed the fuel pressure regulator and checked the return line by blowing down it ,and there was no blockage but still the line to the fuel rail blows off,if i take one of the plugs out it will start and revup ,( very noisely ) and then put the plug back and it will start and tickover untill it chokes with fuel and cuts out again , any ideas ????forgot to mention i have also changed the lambda sensor

Hi Tom - could be down to the temperature switch. What makes you think the car is overfuelling.

If the fuel line to the injectors is overpressuring to the point it is being blown off then I would suspect that the fuel pressure regulator has failed in a fairly significant way.

The flow of fuel per duty cycle would be correspondingly higher and would therefore cause overfuelling.

I would agree with Carrera - sounds very much like the pressure regulator is furbarred or its fuel return line is blocked.

It's simple to eliminate the return line from the equation - simply disconnect it at an appropriate place & allow the fuel return to empty into a suitable container. No fuel = blockage

You could even do this by bridging the fuel pump relay instead of cranking the engine & measuring the amount of fuel coming out of the return pipe. This is the method for testing the delivery from the fuel pump. I don't know the spec for a Clio but it will probably be around 0.4-0.5 litre fuel in 30 seconds
