Yes the fuel tank has to come out to change the fuel pump. But are you sure that is the problem ? Your vehicle has a Fuel Pump Flow Control Module (electronic's ) Or is it just your fuel level sensor you want to replace ? And to your question of if the fuel level sensor is bad will the car shut down if the gage says it is emty but it is not? No ,this will not shut down the vehicle. You probably have no idea of the complexity of the electronic's involved an the thing's that can cause the gauge not to work .
Fuel Gage
The instrument panel cluster (IPC) displays the fuel level as determined by the ECM. The IPC receives a serial data message from the ECM indicating the fuel level percent. The fuel gage defaults to empty if:
• The ECM detects a malfunction in the fuel level sensor circuit.
• The IPC detects a loss of serial data communications with the BCM
• The BCM detects a loss of serial data communications with the ECM
When the fuel level is less than a pre-determined value, the low fuel indicator illuminates in the IPC.
Unless you have a factory or professional type scan tool your better off taking your vehicle to a qualified repair shop.

Fuel Gage Inaccurate or Inoperative
Circuit/System Description
The fuel level sender changes resistance based on the fuel level. The engine control module (ECM) monitors the signal circuit of the fuel level sender to determine fuel level. When the fuel tank is full, the sender resistance is low and the ECM senses a low signal voltage. When the fuel tank is empty, the sender resistance is high and the ECM senses a high signal voltage. The ECM uses the signal circuit of the fuel level sender in order to calculate the remaining fuel level percent in the tank. The ECM sends the fuel level message via the serial data circuit to the body control module (BCM). The BCM sends the fuel level percent to the instrument panel cluster (IPC) via the serial data circuit for display on the fuel gage.

If the master switch will open and close the windows and the rear switches open them, won't close them, replace both rear switches.

Look straight down by the oil filter in the front. It is next to the oil filter. There are two alum pipes coming directly off the compressor.

The front motor mount and the upper engine strut mount both commonly fail. Start engine and have someone rev engine and let off while you look to see if either mount is moving excessively. The noise you are describing it is likely either or both the mounts.

should a tenant have to tolerate a putrid odour from an outside vent caused by natural gas?

JUST A NOTE til U get your answer. Some of these GM vehicle has an electric power steering pump, to be Factory service and check only. Check owners manuals.

It does not inflate. It uses an electric motor that pulls a spring together. You need to remove the seat back and check it for power and ground signal but it is most likely broken and needs replaced...

Not prewired. Will require wiring, relay, and bcm programming for control.
