Hello thank you for coming here and reading my issues.
I have a 1992 Jeep Cherokee XJ, the other night i was driving home and i noticed after 4 miles on the highway she started overheating. I pulled over, let her rest and started her back up to finish driving home. (I live in the middle of nowhere and it was 2 AM) I only had a mile to go. when she started overheating again i put her in neutral, turned her off, and coasted her in the drive way. However before reaching her parking spot she idled low and shut off.
The next day she didn't want to start. When I popped the hood, I noticed the heater control valve had split in half. I replaced that issue and checked fluids and still no start. I replaced the CKS and still so start. Also replaced the battery with the brand new one. Still nothing. Checked the spark plugs and I noticed that one of them is not getting fuel. I am a intermediate mechanic, but I am stumped. She has 81,000 miles on her after her motor rebuild in 07.
I also replaced a portion of the wiring harness that seemed corroded horridly, that is located under the battery. (is the one that grounds to the alternator).
The starter cranks, and im only getting small spark.
Any advice would be amazing.

Do you own a compression gauge...also only 1 plug not getting fuel shouldn't totally inhibit a start also is CKS the crank sensor in the bellhousing or the cam sensor in the distributor

Dump some fuel down its throat n see if it starts.
