You should have a red/white going to each injector which is 12 volts. Then you should have Brown/(wht ~ 4, blu ~ 3, grn ~ 2, yel ~ 1) for each injector where the Brown/white is Cylinder #4 and on down with each color I listed. The injector works with 12volts constant and the DME grounds it to fire a pulse. When you checked voltage for me you verifed we have 12volts at red/white so that is good.
You should not get an accurate reading from any injector plug terminal since it is 12volts positive and a open circuit to the DME. That circuit (or Brown/(color for cylinder)) would be grounded only if the DME was firing the injector, if it was firing an injector you would see 12volts for a micro second.
Check an injector for resistance to ensure the coil is not burned out
