is your throttle body idle hole clogged? if you have fuel and spark the only other thing you need is air to start. unless your engine is not turning over. when you run the starter does it actually turn over the engine?

Don't mean to be a dick, but you don't know whats up with your fuel system. Like I said on your "sensor" thread, your guessing. With all the crap you've already put down the bore I'd recommend you get a new TPS and O2 sensor and finish testing the fuel system.

On the other hand, if you don't want to take our advise, just follow freegdr's advise and have it towed to a shop.

I find it hard to imagine that you're not getting it to fire with starting fluid if you have good spark.

put a compression test to it......but unless you jumped time on the timing chain (uncommon on 4.0) you should run..are you sure you have injector pulse just because you have pressure doesn't mean the injectors are firing

WOW that is important.....if your plugs are fuel soaked then you have no spark or very weak one...and my grandparents had an intermitten shut off problem it ended up being a broken wire in the main harness on the firewall it took weeks to find
