Cycle ign key from off to on position. SES light must light up turn on for about 1 second and blink off. If it does not turn on - check main ECM ignition fuse next to your battery.

Re-verify fuel pump and fuel pressure.

Check injector fuse - just to make sure that it is not blown. The red wire on TBI post should measure +12V with key in ign on position

Check and see if you are getting spark when engine is cranking. ECM must receive DRP signal from distributor to operate Injectors. If you are not getting spark or if tach is not wiggling during cranking either ignition module or reluctor coil inside dizzy are gone.
