It will be a wiring issue or ecu problem but not the actual injectors themselves.

apparently none of them work wont even splutter into life totally dead!!!!!!! does this mean the ECU is dead as the fuel pump lights etc all work.

The fault could lie anywhere in the fuel injection system. My guess would be a power/earth fault (maybe from a blown fuse, failed relay or wiring fault) or wiring fault in the spark signal from the dizzy to the ECU. Since the fuel pump is priming this suggests there is at least some life in the ECU which makes the spark signal the most likely candidate IMO. This is a single wire which runs from the ignition module, along the near side rocker cover and into the passenger side footwell via an inline filter. Perhaps the filter has failed or come disconnected?
