The power comes from the MFI relay so that is there and working .

Now the ECM grounds the injectors ECM is new so check the wiring harness and connections .

So you have a problem with the wiring harness from the injectors to the ECM.

Check following wires from injectors to ECM .

Injector #4 Red / Yellow.

Injector #2 Orange .

Injector # 6 White / Red

No just one MFI relay .as said the injectors have power from the MFI relay and are grounded with the ECM with

signal sent by the cam and crank sensor .

USE a LED test light on the three wires at the ECM when the car is running or cranking you should have a blinking LRD light .if not blinking then possible bad connection or ECM.
