Injector wiring

[Travdb96]

I'm having an issue with my number 3 injector not firing. Does anyone know if I can use jumper wires from another cylinder to run that injector? If not, does anyone have a wiring diagram showing what pins on the pcm the injector wires are connected to so I can just run new wires? 1997 2.3l manual

The injectors should all share a common power. The PCM will ground them individually, so you need to determine if you have a power issue, a ground issue, both, or neither.

I have power, so I'm assuming it's a ground issue. I know the pcm grounds the injectors, but where is the grounding location for injector 3?

Bump. I have continuity from ground side of injector plug to injector 3 control pin on pcm. How does the pcm ground the injectors? I'm assuming it's a common ground wire coming out of the pcm and there's some sort of switch in the pcm to control which injector is grounding. If that's true, I'm assuming this is a pcm issue? All injectors are firing except for #3
