what is it that you want to measure? you can check for injector signal right at the injector connector.

Unplug the injector connector. the pink wire should be battery voltage with the key in the run position. the fuses for the injectors are INJ1 and INJ2 in the dash fuse box. So, since the pink wire is the power what ever the other color wire is, is the ground wire from the PCM. the Pcm is behind the right side of the dash. If you measure between the injector power and the injector ground at the connector and have some one crank the engine you should see if the computer is supplying the ground to complete the circuit. Or just put a test light to the two wires for the injector and have some one crank the engine and the test light should flash when it gets the injector signal. Each injector has a different wire at the PCM. Connector2 pin 9, 10, 11, 12, 13, 17, 18, 22.
