On my 05 Silverado 1500, truck was driven to work in the morning and when time to come home it was a crank no start. I’ve gone through grounds (all look good) fuel pressure ect. Checked for spark and the plugs are not sparking. And no fuel smell at the tail pipe. While going through everything, my remotes (both are less than a year old) stopped unlocking the truck, but lock it just fine. No MIL but it does have a code U1041 lost communication with the electronic brake control module. All fuses and relays are good, I’m at a loss with checking everything I can.

Anyone else ever had this issue if so what was the cause?

 

Tried starting after disconnecting the cam sensor which allowed the engine to crank long enough for an excessive crank start. Replaced the cam sensor and back to running. Now I have the Anti-Theft light on.
