Start by confirming that the Crankshaft Position Sensor is wired/connected properly. This sensor sends a signal to the ICM which triggers your spark, and if it is absent, it will also cut fuel. Always start with spark problems, then fuel.

Each injector has a common hot wire for power (example grn/blk), controlled by a NPN driver in the ECU, ensure that there is 12V present at each injector power wire and body ground, if not, check your fuses and the injector wiring to the ECU. You will not be able to determine if the injector is firing with a multimeter alone. Check the coil primary for 12V with the key in the ON (II) position by probing the blk/yel wire on the distributor connector and body ground. Let me know what you find.
