Message is OK you'll need to check the ECU connector to verify it's seated correctly on the ECU. Would also need to check whether or not there's continuity between the ECU connector and the connector in the engine bay (pin on injector plug that DOES NOT have the +12v). AutoFAQ section has color coded wiring diagrams with wiring color codes. Wire continuity can be checked using a digital voltmeter.

If there's no continuity you may have to run another line from the ECU to the injector connector....
