Fuse 29 in the rear seat fuse panel is for the ignition switch. Fuse 33 is for the HVAC. They are next to each other (on an angle). You were working on HVAC and you are now having a problem with starting. Chances are you bumped, dislodged and/or damaged fuse 29.
I would start with looking at fuse 29. If the fuse is good, pull it and use a multi meter to see if you are getting voltage across the contacts.
