I would suspect that you have a bad ECU. If the injectors are firing and the tach is responding while cranking, then the CPS is putting out a sufficient signal. Since you have ruled out the other components of the ignition system, that leaves the ECU. Was the non-start condition sudden? Perhaps the ECU was damaged by the ecco junk wiring while it was still in the car and now it has failed.
Floobydust: a contemporary term derived from the archaic Latin miscellaneous, whose disputed history probably springs from Greek origins (influenced, of course by Egyptian linguists) - meaning here "a mixed bag." - National Semiconductor Audio Handbook
