This happened to me in the late fall of 2007. What fun that was.
What you have to do is remove the smog pump by first loosening the clamps
and taking off the hoses from the back of the pump. Next, loosen the
tensioner and take off the belt. Once the belt is off, then you need to
remove the lower bolt which the smog pump rotates on. After this you will
be able to take the smog pump off of the motor.
Once the smog pump is out of the truck, there should be three allen key
bolts that allow you to take off the back half of the smog pump case. Once
that is apart, you will see a barrel that rotates around within the smog
pump. The barrel houses a set of three vanes, one of which is most likely
broken. This is what typically causes the smog pump to seize, broken vanes
catching between the barrel and the interior case walls. Remove all three
vanes and reassemble the back half of the case onto the pump. Presto, you
have a gutted pump that will serve as an idler until either a proper desmog
is performed or you purchase a new pump.
When I got to this stage in gutting my smog pump I found that the case had
warped and would still not rotate with the vanes removed. If you find that
this is the case, you need to either source a new smog pump or an idler
pulley such as the one that Jim C sells.
As a last note, one does not need to gut their smog pump on the side of the
road just to get home. If you take the smog pump belt and change it's path
to go from the alternator, around the water pump and then to the crank you
can drive home perfectly fine. The power steering pump and smog pump will
not have a belt on them at all, so it will be slightly harder to steer, but
the motor will run and the truck will drive just fine.
Good luck with the repair!!
