    Does the cold start injector and fuel injectors require the same fuel pressure to open ?

    IIRC, the K/KE "cold start injector" is really just a solenoid valve that is normally spring-loaded closed and opens when current flows in the solenoid coil (so not really like a CIS injector -- i.e., there is no minimum "opening" fuel pressure required).
