Hello OK if the noid light isn't flicking then the ECU isn't sending the firing pulse to the injector, this is either down to a faulty crank signal or lack of power to the ECU or a faulty ECU as you've already replaced the crank trigger then next check you have power to the ECU, using a meter on the fuse with the ignition on, if there is power then check that the small earth connections to the enginethese will run out of the wiring loom and end in small ring terminals that are secured to the engine if this is OK then the ECU may need to go off for repair try these firmshttp://www.ecudoctors.com/ http://stores.digitalautotech.com/StoreFront.bok
