Negative Battery Cable

So recently I had 46-48psi fuel rail pressure which seem kind of low, replaced the negative battery cable and I’m now at 54-55 psi, hope this helps, knowing psi should be at 58psi

46 psi is 100% normal at idle. The fuel pressure is controlled to high pressures with given conditions.

Replacing the negative cable was a great preventative step, but I doubt had anything to do with the changing fuel pressure.

Changed it as well cause of some subwoofers that just got installed, did help with my lights dimming, have you tried the zzp big 4 cable kit by any chance?

The big four is for a Sonic, the Cruze uses a big three.
