Your story is a little hard to follow... I don't understand how the engine would be running and idling without fuel (unless it is running off puddled up fuel on the cylinders from running to rich, which I doubt). If you know that you have spark and compression... does the fuel pump prime? If so, I had a similar issue with my old SR20 and I ended up taking the entire fuel rail out (leaving the side feed injectors in the rail) and crank the motor to watch all four injectors spray. Also, inspect the lower o-rings that seat the injectors in the manifold. These are commonly damaged during installation/reinstall.

I'm not sure if you have already done this, but you can try narrowing the issue down to a specific cylinder by running the car and removing each injector clip one by one to see if the engine changed. If it does not change, that cylinder is your problem.
