Help please
I was recently gifted a 2009 HHR LT 2.4L. While on the way to work Friday, the car suddenly began to shutter then the DIC stated, "Reduced Engine Power", "Service ESC/Traction", "Service Airbag", "Service Power Steering", "Low Fuel", and "Engine Disabled". I was able to pull over. I immediately shut the car off and attempted to restart. No crank, no start. DIC displayed "service power steering", "service ESC/traction", "Service Airbag". Called the tow truck and got it sent home. Started researching and then bought a new battery. Still no start and no crank. I decided to check fuses. All were fine. I did notice that the Fuel Pump Relay fuse will rapidly click and will go away when unplugged. The BCM fuses appear fine as well. I plugged my reader and the only code that comes up is U0100. I am struggling on what to do or where to go. Any help would be greatly appreciated.

U0100 means that B+ is open. First thing is to check where the large red wire attaches to the underhood fuse box. Then check the ground point on the top of the trans near the oil filter and on the radiator support above the driver side headlight.
If you can find any past info it would be helpful.

The rear red connector is the power steering, the LARGE red is the main battery connection. It sometimes corrodes or gets loose.
There might be a bad pin on the ECM connectors, sometimes one or more get pusshed out the back of the connector.
If you had the same issue in another car, what was the cause/fix? Did the same person work on both cars before it happened?
This youtube illustrates how to take the fuse apart and inspect the internal bits.

Looking at them will do no good - you have to take the fuse panel apart as noted already and reseat it as per the instructions. The battery cables should be disconnected and checked for corrosion and cleaned up.
