Pulled these 2 codes today, no CEL came on. The P0190 is of course the Fuel Rail Pressure senor malfunction. And the P1233 is the Fuel Pump Driver Module off-line.

The car is running a Vortech supercharger w/ FMIC, Dragon plenum + throttle body, Magnaflow X-pipe and exhaust. The car seems to be running fine. Oil pressure (via the stock guage) is reading fine, a little on the high side. The aftermarket guage is ****ed up and only reads once in awhile.

I checked the FRPS sensor and it seemed clean, I don't have access to a voltmeter and may just go out and replace it.

But what about the P1233? Any ideas on how to remedy this one?

By the way, the car has CPR fuel rails and Motoblue stainless steel braided fuel lines.
