I'm not 100% sure but here's what I have...
Fuel pump works and there are sparks at the plugs. Car cranks, but won't turn over. I think there must be an issue getting fuel into the cylinders and since I have good fuel pressure I'm thinking it's the ECU....
There are several other places I'd look prior to ECU replacement.
The main ECU ground from pin 13 grounds directly at the battery ground terminal, I'd start there, looking for loose brown wires, clean any corrosion, repair all corrosion damage.
The ECU has it's own fuse and relay separate from the fuel pump circuits. That you have spark is a pretty good indicator the fuse and relay are good too, check fuse S17 anyway, it's just too easy.
I'd sure remove the large intake duct between the Air Flow Sensor and the throttle body, look at and through it for cracks and splits while flexing it in all directions, use good lighting.
Check for power on the red wire to/at the injectors, it should be hot continuously whenever the fuel pumps run.
If you have a two color LED tester, you can check for an injector signal on the brown/white wire to the injectors.
Have you checked to see if the cam or distributor timing has jumped?
A fuel pressure check directly at the fuel rail is a real good idea, there is a convenient test port right on the rail. (Oops, I see you've stated you have good pressure, I hope tested with a gauge.)
Have you checked for a plugged fuel filter?
Ummm, have you maybe disconnected the Air Bag controller?
List above is not necessarily complete, nor is there any particular order, it just came out that way.
