1999 Renault Megane • 75,000 miles

Hi I have a renault megan 1.6 petrol on a T reg whitch is struggling to start
it has had new plugs and fuel filter, the cam sensor checked and the adaptions and idle controll valve reset, the ecu has been tested.
the car will start after cranking for a few seconds but then runs lumpy like a misfire and then stalls and then to start it again you have to keep your foot flat down on the gas and crank it for a good couple of minuits and the oil smells of petrol?

Check fuel pump pressure.
