No signal to the coil pack? If the coil pack isn't turning 'on' then the main power to the ecu, injectors won't be there. Its supplied via a relay (can't remember which 1), and it should be the the solid black on the coil plug. Also check the red/blue wire on the injector part of the loom for 12v with ignition on. If the coil isn't being switched, i.e, has power to it but the ecu isn't switching the relevent side of the coil on, check continuity between the coil plug and the ecu plug, should be black/brown, black/blue, black/green.
