4 weeks ago my car developed a fuel pump fault. Had the fuel pump, sender & filter replaced. Following this the car refused to start. The new pump is feeding the fuel to the rails & the car is trying ever so hard to start. It is turning over but will not catch; had recent service before the probs and all coils changed 8 months ago. Tdc & maf sensors checked, icv and egr also checked and seem fine just will not start, somebody please help me?

Fuel pressure seems within the necessary parameters, as for the injectors pulsing that would have to be established. I have also been told that there is a fuel sensor which controls the pulse of the injector which could also be the prob.

Anymore help would be greatly valued

Check the immoboliser is OFF. If the dash light is flahing fast it is still ON or there is a fault. The immo system kills fuel injector function via the cars PCM/ECU
