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?

I run my own kit. I call it the Big 1 upgrade.

I run an extra wire from negative battery cable frame bolt, to the head of the engine.

also if you have the tool just re-crimp the negative cable on the battery end. (find an electrician with a high press.) That fixed my odd problems.

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