OK, I'd say you have a short, and a big one at that. Can you troubleshoot circuits? If yes, start at the engine compartment relay box and start checking fuses and any fusible links or circuit breakers in there.
Please see my tip at http://www.fixya.com/cars/r5925550-dead_battery_troubleshooting . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info. If you find a bad circuit, I can pull your wiring diagrams and tell you where to look for the short. Please remind me what the z71 means--this is a Sierra, right? Do you have dual batteries?

There are some possibilities which you
will have to check in this case:--
1) First of all check the power and
voltage to the battery. With meter it will show exact 12 volt if the
battery is charged. If the voltage is less get the battery charged at local
auto repair shop. If the battery is internally drained and not getting charged
then its time to replace the battery.
2) When you crank the car do you see
spark coming at the spark plug? If no then its time to check the spark plugs
and coil pack. If the spark plugs are not worn out and looks new then its time
to check coil pack. The spark plug gets power to spark from coil pack.
3) The other thing to check in this case
is the starter solenoid of the car. If the battery is charged and you start the
car then it gives power to the starter to start the car. But if starter is
faulty or not connected properly then car will not start.
4) The other thing to check in this case
is fuel in the car. If there is fuel in the car then check the blockages in the
fuel pump if the fuel pump looks proper then check the fuel filter above the
5) If all the above possibilities
mentioned above checked out OK/perfect then it's a electrical issue and
the wiring's in the car needs to be checked. The car gets
power from the battery to get started. so the wires from battery needs to be
checked one by one.
