When you drained the coolant, did you get any on the opti? You may be loosing the pulses from the opti? Is the Ignition Module getting pulsed from the PCM?

I wouldn't put every thing together before testing the opti, this can be done by connectind the wires and rotating the opti by hand while ignition is on, there should be spark and injectors pulsing.

Check if you have spark at the coil wire. If you have spark there but not at the plugs its your opti... Go over all wires including opti harness etc...
