A few weeks ago, I noticed the oil pressure reading " -- -- " and with 115k, I figured it was the sensor. I replaced it with an AC Delco sensor, PN 12673134 today and it's still not reading anything. It shows the same " -- -- ".

What would be the next thing to troubleshoot? Wiring continuity check?

Check that you didn’t install the old sensor back in?
That definitely didn't happen. Old sensor has a tan top, new one has a black top. Plus I mangled the threads removing it from the socket.

I can’t seem to find a wiring pinout on google right now, but I know I’ve seen one recently. The sensor connector should have 5V, ground snd signal. All go straight to the same ecu connector. You could first check for 5V. Then check continuity on the signal wire.

Also, if you have hp tuners. See if it datalogs oil pressure. If it will log but not show on the dash, it could be a cluster issue or canbus problem.

Oh hell no, I’m not clicking your link, not after the last time.

Fool me once, shame on you, fool me twice, shame on me.

Nope. Old sensor and connector are clean.

Well.. it's working now but I didn't do anything. I plugged in HP Tuners and it was reading fine. I looked at the dash and it's reading there too. I know I seated the connector a couple times to make sure but no idea why it's working. Not complaining though.....

Thanks to everyone who commented. And @Karch, did you see the video yet? :p
