What do you mean you had low voltage on an injector? How did you come to that conclusion?

Here's the pinout for the IDM connector.

Check the resistance from the commons (pins 23 & 24) to the corresponding injectors. They should all read in the neighborhood of 3.0 - 3.5 ohms. This will verify the complete path between the IDM and each injector.
