I swapped out a 2011 NA V8 that blew a gasket. New engine worked fine no issues. Next day upon startup it won´t start
I am getting pictured codes P0258 P0560 B10AC82
Greatly appreciate any help

 

Interesting array of codes. Not sure if this might help but I recently ran into a bunch of unrelated codes stopping my car from starting, powered up and pressing the start button with the brake did nothing but center instrument cluster displayed "Ignition on". In the end I traced it to a corrupt Battery Management System. Re-flashing the BMS initially solved starting that night but would do the same no-start in the morning with more random codes. I found that if I re-flash the BMS, started the car and let run for a few minutes, turned off and disconnected the negative post on the battery for 5-10 minutes then reconnected and started the car. My codes didn't come back. The battery in the car was only a couple of months old but we had a cold spell and my wife needed a boost, I was able to trace the odometer reading to the start of the code problems to the time when it was boosted.

 

By boosted to you mean you connected your cars battery to your wife´s car to start hers up and since then you battery was the culprit of the problems? funny because I too recently swapped out a battery.

 

That is the idea, I actually wasn't the one who jump started (Boosted) her car, a tow truck did and at least he knew not to clamp directly to the main battery but essentially that is what happed and how my predicament started.

Also, I have a Topdon Ultradiag that I used to reset the BMS as a reference.
