1995 Geo Tracker 16 valve. The #3 injector was dumping fuel into the cylinder. So I replaced all 4 fuel injectors. And now I’m still having the same problem with the #3 injector. Tested the wire from the ecu to the injector and it’s showing continuity. We tested the main power clip to the fuel injector for the #3 it’s showing continuity. So we cut the wire before the fire wall and the wire to the ecu shows continuity and the cut wire to the injector is showing continuity. Any help would be appreciated
Disconnect the injector, carefully
back probe the control wire at the control module, then use a dvom set to ohm to check for continuity to ground. One probe to the control wire and the other, to ground. There should be no continuity to ground. If there is continuity to ground, unplug the pcm connector and see if the wire no longer has continuity to ground.
