My 1997 Pontic Sunfire will not start after installing aftermarket stereo!

Here’s what happened.....yesterday I was installing a new
double din aftermarket stereo. I connected all of the wires
correctly and according to the instructions. I started the
car up during installation to ensure that the battery was
not dead due to keeping the door open and continuously
keeping the ignition in the on position to check the stereo,
and it started with no problems. However, the stereo was
not working, the ignition wire to the stereo had no power
so I disconnected the cigarette lighter and ran it to the
ignition wire of the stereo. The stereo works great, but
now the car will not start....no turnover, no click...nothing.
All of the lights work, every single fuse in the engine and
interior compartments have been double checked and are
good, recharged the battery 100% and it still will not start.
I did notice that there is an initial click sound just behind
the instrument panel or firewall and then it stops, also
there is a strange smell that seems to be coming from
around the steering column as well. I’m just at a loss and
need someone’s advice....from the outside looking in! All
of the lights and everything works, no anti-theft
activation...I’m stumped. Please help!
