95 trans am injectors not pulsing...
I have tried everything on this car but can't figure out why the injectors wont spray...the fuses are good. Could it be the opti? ? Has fuel pressure 42lbs when primed but will not start.has spark....just no fuel.

Forgot to add, the low res from the opti is what tells the PCM where the cam is and it determines what injector to fire and when , no low res pulse no injector.
