Engine no start

Hey Guys and Gals. New member here. I have a headache with my 91 2.3. The car starts, runs a few seconds and then quits. A buddy of mine has a fuel pressure gauge, and when the engine quits, the fuel pressure stays. So it must be spark quiting. I changed the timing belt, so when I was there I changed the crank sensor. Same buddy said it could be the module on the driver's fender, so i changed that, still no go. I also changed the computer and still no luck! What else could there be? I have asked around with my friends and they all said to change the items I have changed. Anybody with any ideas??

Sorry, that module with the dual plugs is what I was meaning. I have changed that piece. From what I have been told, the three pieces I have changed(computer, module, crankshaft sensor) is what controls the spark in that system. What is so weird is that it does start, runs for a few seconds, and then quits. It starts every time, and quits every time. You cannot keep it running by using the gas pedal, it just quits.

I took the car to a shop and the "KOEO" codes are
218 - loss of ignition diagnostic monitor left side and
222 - loss of ignition diagnostic monitor right side. I take it to mean that with that 8 spark plug system, there is something wrong with the coils? Anybody run into this before?
