What will cause the injectors not to fire? I have 38 psi at fuel rail and replaced TPS, TFI module and have 12 volts to the injectors but when I test with noid light it isn't pulsating????

PCM.. it provides the ground for the injector circut.. no ground.. no pulse. Check power and ground to the PCM.. if both good.. id say thats it..
