remove the plug from the injectors and check for 12v with ignition on,the earth is pulsed to fire the injector.

You need to check you've got power to the ecu,also check that all your sensors are plugged in and gapped corectly

The OE setup powers the injectors via the ECU relay, so long as they have a switched 12V + supply, as said the ECU switches the ground.
