The pump is used to inject fresh air in to the exhaust system at the catalytic converter. The goal is for the oxygen to react with the catalyst and heat to burn up any unburnt hydrocarbons left over from the combustion process. The catalyst in your 1985 Suburban probably quit working about 15 years ago. Unless you replace the converter the pump is having zero effect upon your vehicles emissions. Considering your speaking of a 454 cubic inch engine removing the pump will also have little effect upon your engine either. It takes less than 0.125 horse power to turn it. My suggestion is remove the 454 infact in this day and age I suggest removing the Suburban if at all possible The savings in fuel cost could net you a new car payment.

Where is the oxygen sensor located on a 2005 Chev Suburban?

They are in the exhaust system/pipe. Just start at the engine and follow the exhaust back to the muffler and you will see them. They are about 3 inches long with a electric wire hooked to them. They just screew out. I believe ther is 3 of them but there might be 4. just look at the exhaust pipe real good. On the 8.1 engine, two are located ahead of the catalytic converters in the exhaust headers and two in the tail pipes after the catalytic converters.

Location of bank 1 and bank 2 o2 censors on 1999 Chevy suburban?

Bank 1 is the driver's side, bank 2 is the passenger side. Then you will have sensor 1 and sensor 2. Sensor 1 is before the catalytic converter (closest to the engine), and sensor 2 is after the catalytic converter. So Bank 1, Sensor 2 is: the driver's side , after the catalytic converter.
