I had the same problem last year on my 2.6 when i did the headgasket and replaced everything that needed to be replaced. After everything was assembled, it cranked but wouldn't fire. I unplugged the line going into the injectors and there was no fuel going into the injector but there was fuel going into the distributor. Somehow i just decided to push down on the fuel metering plate while somebody cranks it, and then it sputtered to life. I guess i was reallly lucky and that could have been much harder and probably is for most people.
