What have you checked so far ?
Is it getting spark to the plugs ?
Can you spray starting fluid into the throttle body and get it to start ?
Have you checked fuel pressure at the injectors ?

i was once pulling a trailer with a ranger when it suddenly lost power and the engine died. turns out the problem was with the fuel shut off inertia switch. the switch is supposed to activate in case of accident. on my model the inertia switch is located in the passenger side under the glove box. dont know where yours is located. once you find it, just push the button and see if it resets. good luck.
SOURCE: Fuel Problem
fuel pressure regulator? This diverts excess pressure from the rail back to the tank. When they wear out they usually stay stuck open thus diverting all pressure back to the tank. Pressure tests do not reveal this as pressure is checked before the rail not in it. I do believe you have a bad fuel regulator. They are 75US ouch.

these engines did have some exh valve issues, service bulletin 05-26-3. one other thing to verify is that the cam synronizer (CMP) is correctly installed. if its not right on, its way off.

The fuel pressure has to to 35 to 45 psi. And no low fuel pressure will not cause no injector pulse.The veicle sounds more like a idle air control problem why? because as you stated it runs rough when it does start.Get it to start sysle the key you will hear the fuel pump go on cycle it three times then start it up. when the vehicle warms up take the idle air valve out and clean it with carburator cleaner or even brake cleaner you may even want to do the throttle body itself this should help with the hard start up and rough running

Easy fix on this rig. Replace diatributor and tfi module together. What happens is the center contact on the dist. Pickup coil gets eroded and makes crappy contact to the tfi resulting in intermittent running or no contact to the tfi resulting in failure to start.
