RS3 Brushless pump issues

About a week ago I installed an RS3 brushless pump with the A2B harness (Black controller). Everything was running fine until this morning when I was commuting to work and the car lost all power.
I was able to get it to the side of the road, but the car would not start. I had it towed home, did a scan and it came back with the following codes:

P025A Fuel Pump Module Control Circuit/Open
P025C Fuel Pump Module Control Low

Things I've checked:

20A fuse - Not blown
All connectors are correctly pinned
The ground is secured to bare metal

Is there anything else I should look at before I pull the pump out? Could it be a bad controller?

Are your connectors inside the pump still good? Either you have a broken connection or the pump somehow died in a week.

I just looked at my old post when I was having a problem with my setup...I had the same code P025A. It's your control module, it's either not getting power or it fried. I think if it was the fuel pump you would get a "fuel pump Primary" failure, not a control module failure like you have now. Do you have another rs3 controller for a test?
