Yes, that rules out the timing belt and a spark problem. One reason the spark cannot be ruled out with a spark checker, or seeing it on a plug, is with EZK ignition, a fault with the CPS or controller can cause spark to be timed wrong. Not in your case, though, since it ran on starting fluid, the problem is clearly a fuel issue.

Time for a little history. Did the car die on your daily commute? Or is this a project that hasn't run for some time? Given you have fuel pressure you can feel in the return line, and pulses delivered to the injectors observed with the help of your 'noid light, there's only one thing that I can imagine -- your injectors are all clogged. Not an outlandish conclusion if the car's been sitting. Pull a plug or two and sniff, to be sure, then pull the fuel rail. Run the injectors without cranking the engine by using the OBD mode 3 test. The residual fuel pressure after running pumps alone with the jumper will be enough to see them squirt.
