electrical crazy
 

hi i just changed the motor out of an 02 trailblazer. i put an 05 engine in it. i had to swap 02 pigtail but other than that i have everything in place properly. went to start the truck and all dash lights come on but no click of starter or fuel pump just silence. battery is charged and all sensors/electrical and mechanical parts are in the proper place and torqued correctly. i have gone over it 4 times and can not figure it out. also when u remove the key all power stays on i unhook battery to kill power. nothing comes back on until i turn the key again. no door chime all dead until ignition is turned on. thank you for any help
