Have you checked your oil pressure sending unit? Did you accidentally pull the wires off. The oil sending units actually control the engines ability to start in case the engine dies from an accident.

When you stabbed the distributer back on the compression stroke did you make sure the rotor was pointing to the #1 plug wires location on the cap?

I'm pretty sure if your not sending signal to pulse your injectors it's either the ICM which you have replaced or the pick up coil. The pickup coil would actually cause a no fire and no pulse of the injectors.

Also how did you test the pickup coil?
