Renault Scenic cranking but not firing

Running Rough, Starting & Power Loss
i prev reported a prob on this forum, i now have had the AA breakdown people out to look at the car. after checking everything that could humanly be checked (s/plugs, 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 then cut out. the plugs were dry when he removed them and explained they should have been wet with fuel... he aint sure why the car aint starting but says that everything that should work is working... his diagnosis was that the fuel pressure maybe be too low (even though he checked it, and it seemed fine) or that there is a problem at the rail/injectors...
any help would be good at this point... it has to be something simple (surely all 4 injectors couldn't fail, could they?)

this does not seem to be the case, but, lets say it turns out to be an ecu fault, wot r we lookin at worst case scenario?

Hi, this sounds like the problem I had with my Sport Alize last week. Have you had the TDC sensor on the starter checked? Theres a magnet that makes the sensor work (according to Mike my mechanic) and it gets little bits of metal stuck to it. Too many bits and it stops working so the engine cranks over but will not fire. Mike cleaned the swarf off the magnet, put it back in place and off we went! Result! Took all of 5 minutes to fix. Hope this helps, Rex.
