Yes, thanks for this info. I have been able to verify this using my Snap-On MT2500 scanner also. I can turn the secondaries on, although I have not tried it with the engine running. It will also turn on the fans. I guess it turns on everything the ECM controls for troubleshooting.
I have thought about it and although both fuel pumps work, thinking they can have degraded performance, maybe age or from ethanol. I think back to my injectors. Already had low voltage to the pumps from a bad relay. And two new pumps will only cost about $180. When some people sell their cars, they advertise that it has new fuel pumps, so I will see. Thanks.
