Jeep starts but immediately dies

Any update on this. Having a similar issue.

1999 jeep wrangler. 4 cyl. Every day driver randomly died on me. Auto zone bench tested my battery and replaced it bec it had a bad cell. Now new battery is in it starts but dies right ways. Seems to have good connection and grounds. Seems to have a good starter. Replaced relays. Fuel pump holds pressure. Fuses look good. Haven’t looked at any sensors wondering if I missed something. I’ve only had a black key and never swaped keys don’t think my wrangler has SKIM
