Gosh this sounds JUST like my truck, Cricket would do at the start of it's no-start days back in October 2007.
PCV valve, plugs, wires, fuel pump (even though it was reading it was getting fuel initially) and filter, coil packs, and testing of ignition module later, it is now finally back running, but now, a new problem...a VERY rough idle.
I can get it to 55 mph in 5th gear on level land...but even the smallest hill it goes down to at least 35 mph going up it. It is also getting less than 10 mpg right now and going through oil like nothing you've ever seen! (having dad check my husband's oil change this weekend...I think he didn't put the filter on right...he's done it before! LOL)
The one thing that seems to have got it back running was the fuel pump, even though it was audibly and visually (by using a meter) working at the start of all of this.
I don't even pretend to try to be diagnosing your problem...but it is SO similar to what I have been experiencing, I wanted to share what we've done so far in case any of it may help you down the road.
