TJ acts like it has no power

[navy tj]

I am a newbie to jeeps. Last week I'm leaving for work and it's like I have no power. After third try she starts right up. I get to work and everything is fine. Later I go to start it and soon as key goes in the gauges go crazy but won't turn over. So we check things some and I get a jump and starts right up and runs good on way home. Get home completely dead. After replacing battery all seems good until the other day when it starts beeping for no reason and now my left turn signals are super fast but both front and back are working just fast and the right side is fine. Any thoughts

I chased power issues for a bit and finally found a plugged cat.

Any codes? Way to read live data?

Any idea if your sensors are original Mopar?

What's your battery voltage? Can you also get the voltage as you're turning over the engine?

Possibly a PCM issue if the guages are doing weird things. Check with wranglerfix.com.
