If the year is around a '92 the pump is located in the tank under the sending unit for the fuel gauge. They are not the most exciting thing to replace as i have just done one in a 92 S-10 by droping the tank
If you have a V-6 it is easier to remove the bed and access the top of the tank that way. On most V6 Sonoma and S-10's the exhaust is in the way of removing the fuel tank, you can lower the exhaust but then it will rest on the differential and you will have to lower that also. I have a good friend that is a 35 year GM Mechanic, he says ignore the books and remove the bed. There are usually just 6 bolts that hold it on, have some beer ready for your friend that will help you sit the bed out of the way.
Mine is a 98 4 cylinder, you can't buy just the pump. The whole assembly is $330.00. Look it up on autozone. Crazy.....

what are the symptoms of a bad fuel pump on a 2002 GMC Sonoma 4.3 liters?
the fuel pump is a in tank pump, you have to drop the tank, its located inside the tank.
Mounted on top and inside the fuel tank.
No. The fuel system is computer controlled with relays.
No. GM does not use those.
It is inside the fuel tank and can only be accessed by removing the bed or dropping the tank. I suggest removing the bed. You should have help.
You must remove the fuel tank or disconnect the bed and slide it back enough to access the pump, your choice.
DO not do that! Damage the truck! The correct way is to lower the fuel tank out of the truck.
