When you checked fuel pressure, did you use a gauge, or did you just verify there was pressure? What was the pressure?
The other thing you could do is check for injector pulsing. You will need a noid light. Professional noid lights cost app $50 for a set, but if you are good with a soldering iron, I can tell you how to make one for less than $3.
Get a small 12volt incandesent light bulb. Small as in dash light, dash idiot light. Not a brake light blub. And not a led bulb.
Take a 1" piece of SOLID 8 or 10 gauge copper wire, and hammer it flat! Then cut the flat piece of wire into two equal lenghts.
Next get 12 " of 20 ~ 22 gauge stranded wire, and cut that into two equal lenghts.
Solder 1 piece of stranded wire to each lead of the light bulb, and then solder 1 piece of flat wire to the other end of the stranded wire.
Now take heat shrink tubing, and cover every connection, so that only 1/4 inch of the end of the flat wire is not covered.
You can now un-plug one of the injectors, and plug the flat copper wire into the harness.
Try to start the engine, if the injectors are being pulsed, the light will flash. The flashing should be fairly obvious. If you do not see the flash, you will need to check the injector fuses, and then look at the ECU,
If it does flash, you will need to double check your fuel pressure. I believe harbor frieght sells a tester, you need around 45psi (can remember exactly off the top of my head).
But since the car runs on starter fluid, you know that compression is good, and parts of the ECU is good.
