Okay, if you reinstall the relay and turn the key on, can you feel the relay click?

If the relay control side has power to the relay, but does not energize, then it is either the relay or the ground for the control side which is at the left kick panel.

The black wire is the wire from the ECM. The white/black wire is the ground for the control side. That is the current issue we are trying to work with since the relay will not energize.

The black wire is coming from the PCM and then goes through the COR and then to white/black then to G200, correct?

Don't know what to do without you, you been so helpful which pins on the COR. So I can trace the wire and do a continuity test from the black wire to the PCM and black/white to ground. There's 3 wires on the ground G-200 if it checks out we dealing with the computer.

It is inside the relay.

The black wire comes from the ECM and the white/black is the ground at g200.

As we discussed before, that is power from the ECM. With the key on, it should have power for 2 seconds.

Then when cranking, it should have power all the time.

I'm getting confuse here. The black/white wire goes to G200 and which black wire coming from the PCM to complete the control side of the relay. I need to confirm this that the PCM is defective so I get one.

We went over this many times.

The black wire comes from the ECM to power the control side of the relay. It has power for 2 seconds and turns off with the key on.

Then when you crank it, it gets full power.
