Using the OBD mode 3 test of the actuators, you can check the flow of an individual injector by removing the electrical plug from those you are not testing. Remember to replace the ECU grounds removed at the fuel rail bolts.

Don't crank or run the engine, just the residual pressure in the rail will be plenty. If you want to ensure regulated fuel pressure, operate the fuel pumps only using a jumper at the fuse panel.
