When set to ohms, it shows a 1. When the leads touch together it shows .2.

Gary, looking back, I'm not sure he checked that correctly. As you stated, why no 5 dc volts? And I never got confirmation that there is continuity on pin 48.

Someone ask you to post a picture of your meter, are you able. Or what make and model is it?

I actually got rid of the connector and replaced it. It appears to be a good, solid ground.
So, if I wanted to check it for continuity, I would disconnect it from the battery, use the paper clip method and put that into the correct slot in the ECM connector, put the positive lead at the other end and ground the negative lead, Correct?

And I need you to check pin 48 & 46 again.
Disconnect the Pos. Batt. terminal in this case, leave the Neg. Batt. Terminal connected.

Pin 60 should be the Battery Ground pin.

Pins 40, 20 & 49 are also grounds, so check them when you get the chance.
Just be very sure you are on the right connector pins.

With Positive cable disconnected and negative terminal connected, pin 48 reads 1. Pin 46 reads .9.
With negative terminal disconnected and testing continuity to pin 60, reading is .4.
With negative terminal disconnected and testing continuity to pin 60, reading is .4.

Agreed. A reading of "1" is wrong.

If you get a "1" on pin 48, that means you don't have connectivity from the STI connector and the ECA Connector, and that may be why you are missing +5 vdc at the STI self-test connector.
(Is your STI connector Gray?)
(Is your Self-test connector Red?)

Yes, it is gray with a green wire.
I'm heading out myself anyway. So I would rather you work on it when you feel better, always better results.
