If the body module was not installed without a scanner you wasted your money because they are all vinspecific and have to be installed with a scanner any shop should be able to do this. Check the items in pic but it stil may not start due to body module being replaced. Also try resetting yoru anti theft. See pics

But would that control day time run light the horn wipers and the climate control cant find a wire dio to see how the wire harness is run in this vehicle.

Have you tried to reset the anti theft like I asked in first replay? Have you checked any underhood fuses and relays? Headlight have them it can also be your t/s switch or multifunction switch. Check ground rf corner of engine and grounds near headlights. If not that check to see if ignition switch is putting powr out

I have no crank no start issue also. However, my key is stuck in the igniton and vehicle stuck on park. I tried replacing the battery nothing. I tried manual override of shifter got it to neutral still no start. No crank. I swapped some of the fuses nothing changed. The interior lights do not come on neither do brake lights or headlights. When I attempt to start I get no crank no start but I can hear the fuel pump engage.
PLEASE HELP. I'm stuck it has me stumped. I've asked a couple of mechanic friends and they are also stumped.
