Hi, I recently bought a new battery for my truck. The battery is good, but my truck won't start. The push button does nothing, it won't go in to acc or run. There is power but light in the cab doesn't come on and the door does not beep when opened.

It sounds like you have a bad connection at the battery. I don't see any special instructions when you change the battery like a reprogramming procedure. Here is a guide to help you clean the battery cables ends. You may have a bad positive or negative cable which happens. Here are the instructions from the manual in the images below:

If all is good, we should do CAN scan because you may have a bad PDC. You can get a CAN scanner from Amazon for about $30.00.

Here is a video to show you how:

Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.
