Car cranks, but will not start

I have a 1995 Ford Taurus Sedan with the 3.0L non-Flex fuel motor. One morning my fiance went to start the car and it would crank, but not start. I have fuel to the fuel rail (pushed the schrader pin with a screw driver, and got sprayed). I spoke with a local mechanic and he said it sounded like the Ignition module mounted on the side of the distributer, so I replaced it. Still will not start! As the mechanic and I talked the suspicions moved to the coil, I figured with the age of the car and the price of a coil, just replace it instead of testing. So, the coil is replaced, still the car does not start. There was talk of the pick up coil in the distributor, but I do not have the proper tools to replace this. Today I sprayed a little starter fluid in the intake and the car fired right up and ran for 2-3 seconds, then sputtered and died. This tells me that it is a fuel problem. I don't think it is the injectors, as that would be odd that they all go bad at once, or will one bad injector keep the car from starting? My first suspision is the computer that controls the fuel system, but I do not know which one that is as I have heard of on behind the glovebox and I have seen one under the plastic emissions label above the fan shroud. Any assistance would be greatly appreciated.

Also the car has a small leak in the plastic fuel line that runs between the tank and the engine compartment, would air in the fuel line cause a problem like this?

Again any help would be greatly appreciated.

Thank you,
Ken
