I changed the bulb and still wouldn’t work. So, I started looking at the fuses and no fuse was blown so I replaced the connector still nothing. Now I have no crank no start along with

It looks like you have a BCM that is not working, so it can be a fuse not getting power, the BCM has a bad ground or a bad ignition switch. If all of these check out, I would get a preprogrammed BCM by searching google or eBay. Unplug the BCM and then check for power from the fuses and ignition switch. Here is the location of the BCM and the wiring diagrams which show which fuses and wires to test from the ignition switch. This guide can help:

I also marked the ground wire the BCM as well, make sure the BCM is disconnected before testing. The BCM is located behind the glove box. Check out the images (below). Please let us know what happens.
