LB7: #1 injector shorted
Am I right that on LB7s the FICM converts 12v to 96v? Also, with key on but without the engine running, should I be seeing 96v at the injector pigtail harness from the FICM or does the engine have to be running? -

How did you determine which injector was grounding? I have my passenger side valve cover open (dreading removing the driver side) and when measuring the continuity of the injectors they read... #1 = .06 #3 = .00 #5 = .00 #7 = .00 I don't think .06 is a bad reading do you? Or is this a... -
