fuel to injectors but the injectors are not getting pulse to open. from pcm, something is not sending to the pcm, like crank sensor, cam sensor ect.

CPS crankshaft position sensor, just one, cam sensor sensors may have two, but everything has to work together in this area of injector pulse, I think its the security not matching the key chip.
