The inertia wire colors S/B...

DG/Y comming in from the closed 'energized' (hopefully) fuel pump relay,, PK/BK going out to the fuel pump from the inertia.. The GY/O is for the instrument cluster, but don't worry about the GY/O at this point..

Cycle,,, or better yet,, have someone cycle the key to the 'ON' position while you monitor the inertia voltage.. The PCM will be in control of the fuel pump relay and will 'time out' the power distribution in a few seconds so it may take a few cycles to read the voltage.. Look for 12V coming in on the DG/Y, and going 'out' on the PK/BK wires...

You can check for spark up on the coil pack spark plug wire ends with a tester, or use a spare wire ect. or a decent gauge test lead and check for spark 'jump' on a ground location.....
