Can't find smog pump for 99 gmc jimmy sle, help dealer keeps ordering secondary air pump. the smog pump is grey not black.

The secondary Air pump is the smog pump. It's located underneath the radiator support on the passenger side behind the oil filter access cover. and has an extra piece attached to it for air flow from the intake to the output. once you get the bracket out take it apart and you'll see they are the same

I need to replace the smog pump on my 1991 dodge dakota. I looked at the all of the pulleys etc. and can not find which component that I need to loosen and pivot in order to loosen the belt so I can...

If you have the 3.9 V-6, when looking at the engine as you stand in front of your truck. The smog pump is on your right. You will see one bolt running from the front to the rear of the smog pump on the left side. The bolt is about where nine o'clock would be on it if it were a clock. The bolt is a through bolt, and acts as the pivot. It must be loosened and completly removed.
On the right side, at the three o'clock position you will find the adjustment bolt. It comes from the rear of the smog pump to the front bracket. You will see that it does not have a regular looking nut. But, insteed what I call a trapped nut. A design that stops turning when tighten, or loosened by coming into contact with a part, or bracket. After you remove all of the related hoses, etc. the bolts can be removed allowing the smog pump to be removed. Installation is done in the opposite order. The v-belt is also tensioned by "swinging" the smog pump upward.

Smog pump was removed from my 01 s10 and the truck is doggy feeling when i press in the gas. Would the smog pump cause this problem or should i check other things.

the computer is programmed to work with all devices the car came with. yes, removing the pump can cause this. also, contrary to popular belief, removing the smog pump causes your gas milage to go down.
