You should use a Digital Multi Meter when testing circuits on a fuel injection harness. You could damage the PCM if you are not careful.

Checked both pink wires a coil connector both have 12V, on switched 12V should I be getting 12v at each injector?

I don't have a red connector to my PCM only a blue and green. I think green connector pin 9 is for the fuel pump correct?
