I just tested my injector resistance tonight - all seem OK. They were cold though, but all between 12.1 and 12.4 ohms. I'll re-test when hot.
(I'm having some loss of power on 2ndaries..).
If it's any help, I created myself this diagram to speed up figuring the stuff out from the factory service manual:
... it's not as complicated as it looks ... The first relay is easy to get to, the second may need small hands with the battery in place. The ECM of course easy to get to, and the Ignition Diagnosic Connector - as the manual says - is sort of lying on top of the big cable-bunch just by the wiper motor...
