Isn't that the way it goes so often? Brand new part didn't work, and spurs ya towards replacing a bunch of other parts that were fine? Crap..well at least you solved it and can move on. With all those replacement parts in fuel and ignition systems...you are set up (hopefully) with a lot of fun Jeep miles without future issues there. Something to be said for that...but it's nicer when we do it voluntarily, as opposed to chasing down a prob.

I look at it this way damn near everything was tune up parts. So the old girl got a good tune up. Even put on a new filter and an oil change to finish it off.
By checking do you mean you looked at them and said "they look good" or did you pull each ground connection and wire brush it? It makes a difference, they can look good externally but still have corrosion you can't see.
Also check the cables themselves. If they are unknown age/history, then replace them. 4 gauge or 2 gauge, dealer's choice on a 12v system unless you're running a winch, then go heavier. Battery and ground cables can look good on the outside and on the ends but be nothing more than a tube of corrosion on the inside.
Get a fuel pressure gauge and get some readings. Just because it's running doesn't mean the fuel pressure is good. There is a pressure test and a volume test. Usually if they pass the pressure test they're going to move enough volume. The volume test is a little more involved. Seen more than one Jeep that would start ok but run like garbage especially under load and it was a weak fuel pump.
