2.5 Cranks but won't start

I have a 94 2.5L. I was driving between 30-35mph today and it just died. I hardly knew it was dead until I had no throttle response. It didn't sputter or kick. Now I can crank it and that's all it will do. I have checked spark and have it. The coil is good, cap rotor wires and distributer are new.

Some background info, I had a problem just like this a couple weeks ago and it was the fuel pump ground so I've tired that 3 times today and ruled it out. The fuel filter is new but the pump is still from the PO so its 3 years old at youngest. What ways can I check if it's getting fuel? any other tips or advice is very welcome.

I believe that the inlet to the carb. or fuel inject can be unscrew [with the keys in your pocket ] then crank it over quickly , hold the line in a quart jar and see if any fuel comes out, I hope that this are good advise because it been a long time since I work on a car

There should be a shrader? valve (looks like a bike tire valve)on the fuel rail, use a rag and push in the center. If there's pressure in the line it'll squirt out there...Also check the Crank sensor just behind the TB intake going down to the top of the flywheel (if I'm saying that correctly), I had one that had a hairline crack in the wire and every time the voltage would change it would trigger the shutdown relay and kill the engine. Had me stumped for a while...
