Bad Crank sensor ? Good battery voltage
I'm getting 12.48V on my battery terminal. But the Jeep won't crank almost like a DEAD battery.
I'm thinking it's a bad crank sensor. Here is a short video as a crank the Jeep
any help would be much appreciated

Check your terminals and your grounds before you chase any sensors. Don't just look at them. Get rough with them. See my sig.

My understanding is a bad CPS results in a crank-no-start situation. So if you're not cranking, I'd start (after checking grounds and battery cables) with battery, starter and starter wiring testing.

Thanks for the feedback
Yeah, I tested the AGM 6 month battery and it failed so that got be thinking that the terminals on the battery and everywhere else could be the culprit. A few years ago I upgraded all the wiring to 4 gauge wire but the Houston humidity really did a job on them. I brushed them up with a dremel and the Jeep started up right away.
I slightly coated all the terminals with dielectric grease.
