I'd start by cleaning the outside with a household spray cleaner to get the dirt and crap off before you start removing the plugs. Also, check the plugs on other sensors like the MAP and throttle position sensor.

I didn't think of cleaning the connectors. I'll have to do that tomorrow as a preventative measure. As far as the MAP goes, I inspected it, and it seems on the up.

Update. Going to need an ECM. I managed to get the old thing able to start but she's running pretty rough. A friend of mine with the same ECM let me swap to test and it runs perfectly. We were even able to go for a little drive. So if anyone knows a place to get a pretty good used ECM for cheap I'd appreciate it. There's a bunch on eBay, but I'm weary since the parts often have no guarantee.

Same ole jeep new issue.

Ok. So I got my new ECM in the mail today. Works like a dream, fires right up, engine runs like a champ, no die outs, couldn't be happier. But while driving it by myself today I noticed a popping coming from under the vehicle. It was doing this when I first got it, so I replaced the front axles. I'm not really a knowledgeable person when it comes to suspensions and stuff so could this be a bad joint or a tie rod end? I'm honestly not sure.
