No crank No start

[captainhook60]

I have a 07 silverado 1500 with a 5.3 Z71. Everything seams to have power except the starting system when I turn the key to the start position theres no power going through the fuse. I have had this problem before but was able to jump start it but this time that didn't work. I need to know the exact things I need to look at to figure out what's going on. One other thing I only have my spare key and I don't have the key fob either at least not with me right now! will that have anything to do with this issue??

Is there any message on the instrument panel about "Security" or something similar?

It acually does have the service anti-theft system light on now it wasn't at first when it wouldn't start in the first place

This may require a bi-directional scanner capable of CANbus communicatons.

I did the engine not cranking .. then I did the relay to change the horn relay .. then the engine starter works then the horn is not working ............

2 years ago the starter wires connectors are the iron nuts did a corrosion .... then I used a brass/s/steel nut then it works .. my 2000 is the OEM ....
