Well Troy, if you're really bad at fixing cars, you're in good company at least! I had very similar problems on my '95 Spirit. I replaced the fuel pump and relay only to have a completely bizarre no-start. Turns out, I had removed my bulkhead disconnect in an attempt to install a trip computer and not tightened the screw enough, leaving an intermittent connection. It sounds like you've got the same issue. I don't think the Sundance was available with engines that had cam or crank sensors; both the 2.2/2.5 and the 6G72 used distributor pickups. The ECU shouldn't be looked at as a problem until all the wiring checks out. If the car started and ran, it's most likely good (99% chance). Make sure you're actually dealing with a fueling issue too, see if you can get the car to start on ether, carb cleaner, or a little bit of gas. If not, you're not getting spark. Electrical gremlins are a MAJOR PITA and really require a very thorough diagnostic process. Keep at it, and you'll find it.
