the pump is in the gas tank siphon the gas out and remove the straps holding the tank(you will also need to remove the three screws holding the filler neck to the truck box under the filler door.)as you drop the tank you will also need to unplug the wiring to the top of the tank and the fuel lines they are usually plastic clips,but if this has been done before and the clips got broken from the first time they could have put clamps in place of the clips.I have found it much faster to remove the truck box itself and that way you don't have to drain the tank and it stays stationary while you RandR the pump with less chance of breaking anything.
Also did you double check the fuel pump relay under the hood in the relay box,I would start there first.
Hope this helps good luck.

The 1985 GMC Sierra transmission is a th700R4 overdrive transmission. The 700R4 does not utilize a vacuum modulator. Shift points are controlled by the T.P. or kickdown cabe. Proper adjustment of this cable is critical to transmission longevity. Your Pontiac, if originally equipped with a th400 transmission, has no means to connect this cable to the carburetor. I would not recommend this transmission swap. Also the th400 and the 700R4 use different sized drive shaft yokes, so your drive shaft cannot be used.

Replaced the egr value on a 1993 gmc Sierra still doing the same thing any suggestions

Check that the EGR vacuum solenoid is working. Remove the vacuum line to the EGR and there should be no vacuum in that line with the engine at idle.

Now check if the vacuum operated doors work when you command various vents. There should be a vacuum line from the intake manifold that goes through the firewall and into a pod-like device on the back of the controls. From there vacuum lines run to the various doors. See if you still have a vacuum signal from any of them.

Heater control will be set on defrost but air comes out panel or switches. floor air is very little.

Sounds like you probably have a bad vacuum line on the back of the heater control. If you remove the heater control from the dash, you will find a vacuum hose cluster attached, you may either have a vacuum line that has come loose or one that has a hole in it. If you don't find either of these problems, then you may have a bad heater control, but I would look for a bad vacuum line first.

I have a 2002 GMC Sierra 1500. 4.3 liter engine. I brought it to autozone and they put the gauge on it and got two codes P0140 and P0300. I had my distributor cap replaced, ignition rotor, plugs ,wires,...

Clean mass air flow sensor with a nonchlronated brake cleaner,install new air filter and check all vacuum lines for leaks then check for vacuum leak around or at intake manifold.Code P0140 is for mass air flow sensor code P0300 is a multiple misfire which more than likely is a vacuum leak possibly intake manifold gaskets leaking.

I have a GMC Sierra 4x4 and can't get the transmission to shift out of first gear. What could it be?

There is a modulator valve on transmission that has a vacuum line attached to it that may be bad or a broken vacuum line.

Where is the pcv on 2002 gmc sierra

PCV (positive crankcase ventilation)valves are almost always located on the valve cover.
I can not tell you positively where it is on this truck. It may be in the line that goes back into the intake cowling.
