So I took the GT for a nice cruise the other day.. It was running fine though I've been suspecting its been a little down on power. When I went to take it for another cruise, all the car does is crank. I've pulled all the fuses (fuse box in engine bay/inside car) and nothing appears to be the issue. I then checked the shrader valve (sp?) on the fuel rail and it has fuel in the system. The fuel pump is priming. I sprayed some starter fluid into the intake but it still doesn't want to turn over. The battery is clean with secure connections. I've unplugged/replugged MAF sensor. No wires appear to be unplugged anywhere... I guess maybe the distributor? Any other ideas of what it could be? I also checked the intertia switch/connector.

Well 98 does not have a distributor. It uses a crank trigger. There is a little more to the system than that. But check the plug on the crank trigger. If that visually looks OK then you need to check to see if the plugs are getting spark.

Okay, so where is the plug on the crank trigger and where is the crank trigger? I'm trying to pull up pictures/videos but all I'm seeing are the coilpacks/plugs. The crank trigger appears to be a "gear" like looking thing? I'll also check the plugs for spark (take them out, re-attach to wire and see if they spark against metal part of engine bay)

Forget seeing the gear or any of the workings. You would have to disassemble a portion of the front of the engine. It might be easier to see it if you jack the front of the car up. Just to the left of the harmonic balancer you will see a little black looking sensor type thing pointing at the passenger side of the car. It will be angled down and have a couple of wires hanging out of it. Just make sure its plugged in and the the wires are in good shape. If everything looks good there then chances are its fine and you can concentrate on spark at the plugs.

So interesting thing happened yesterday. After unplugging the plugs on the coilpacks and replugging them back in and removing a spark plug in order to test it... The car magically fired back up and ran good... Like. Real good.

sounds like you had a bad connection and its great that its fixed, for now but smart money says it will be back. Next time give the connections a good tug/pull/push on the harnesses and make sure they do not move much. If you can see movement there is a problem but doing this to selected wire harnesses and then trying to start the car can help you diagnose which is your problem.
