    Anyone encountered low side fuel pressure stuck?

    2015 z06.... When scanning I will often see lift side fuel pressure flatline to 57.9psi and not vary at all for long periods of time. Randomly it will come back 'online' and start to vary again as expected/commanded with a PWM pump.

    I unplugged the sensor and even then reads the same 57.9. Tugging on wiring harness has no effect on readings. GDS2 shows the same as VCM scanner. Starting to think I have a bad pcm? Any experience here?
