right guys need some help here ive fitted a new engine in my saf it was running be for i fitted it and my old one was running before i removed it anyway tryed starting it tonight and i have no spark and the fuel pump doesnt work?? ive changed the crank sensor and i fitted a direct live to the fuel pump which made the pump buzz?

 

I had the same problem yesterday,i don't own a cosworth but my car's fitted with Pectel super 8.
Check the phase sensor wires carefully,mine had both snapped inside the rubber boot resulting in no spark...
1 other quick way to check to see if the wiring is ok is to turn on the
ignition and disconnect the plug to the phase sensorthen re-connect the connector,the pump should prime,same thing goes for the CS,if a lug passes the sensor it should fire the pump and click both relays.
