Spray a shot of starting fluid in the plenum ( pull a hose off the side, give a quick squirt reattach hose) then fire it up. If the engine starts and dies shortly there after then your injectors arent responding to the ECU "fire" signal. If thats the case you can double check the circuit by rigging a 12v light to hook up to the injector plugs. Then turn the engine over and look for the test light to start flashing. If no light when ignition is on, then your power supply isnt reaching the injectors. Constant light is good, means power is getting there (they are hot with ignition on and are triggered by the ecu switching them to ground btw). Trigger wires are the white and white/red running between injectors and pins 10 and 20 of the ECU.

Double check all grounds especially the one that is at the intake plenum/manifold junction. IF all ground are good, pull apart the harness for the injector leads and redo the butt connector that ties all 4 injectors together. Common failure point on all 22R-Es. Its located approximately 12" up from where the #1 injector wires break out of the main harness. Cut/clean the wires and resolder them...slip shrink tube on prior to soldering of course to protect the repair when done.
