Question
How much labor is involved time-wise in replacing the fuel pump? Will I have to have the entire fuel pump assembly replaced?

Answer
Hello,

It appears you are asking for an absolute answer to a question that has so many varibles.
If you are doing it yourself and have no mechanical inclination. If you have the mechanical inclination, but don't have the needed tooling. If you are located in the rust belt with the possibility of snapping off the tank strap hold down bolts If the fuel tank is full or empty. There are more that haven't come to me right off hands.

If you have a decent rolling jack and a piece of wood and hopefully less than 5 gallons (1 gallon weighs approximately 8 pounds)and you are not dealing with rusty hold down strap bolts, it shouldn't take more than a couple of hours or less.
You need to replace the fuel pump assembly and make sure you get a new sock as well (Very fine filter that goes in the fuel pump inlet). You need to get rid of all of that gas. Make sure there is no sediment in the tank.
The job itself is not a big deal. It's just the variables that are a problem.

If it has not been changed or if it was change and still having a fuel supply issue, change the filter too!

Good luck!

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
