Fuel injection wiring diagram to ECM

[87chrisss]

Have no pulse on injector #3 cylinder need a diagram which shows me the correct wire for #3 injector on ECM i have tried two spare ECM's and two different chips, still have no pulse. Has to be a wiring issue checked the injector harness the plug looks good, pins also looked good. Any advice? Big plug small plug need some type of location on the plug to ecm to check wiring/plug. Thinking it can be making a bad contact. Is it a brown wire?

Is there battery voltage at the injector plug?

Yes. We checked wiring fixed a few broke wires. But #4 injector isn't getting power to it.

Sounds like a new injector harness should be on the list. Don't take shortcuts or bad things will happen.
