2001 Renault Scenic this damnable Renault Scenic (no offens

I prev reported a prob on this forum, I now have had the breakdown people AA out to look at the car. After checking everything that could humanly be checked (splugs, coils, tdc sensor, fuel to rail, even the fuel pump & connections etc), the guy sprayed easy start into the air intake, the car started but the cut out. The plugs were dry when he removed them and explained they shouldbe wet with fuel. He aint sure why the car aint startin but says that everything that should work is working. His diagnosis was that the fuel pressure me be too low (even though he checked it) or that there is a problem at the rail.

any help would be good at this point. It has to be something simple
