Yes i would say it is a selonoid in the trans or a bad electrical connection. Get under it and pull the electrical plug off trans. If it looks corroded clean it with electrical contact cleaner. Be Very Careful when hooking it back up.Do Not force connection back together or you will bend pins.
Ignition key won't turn
Try turning the key while jerking the wheel left and right and depressing the brake pedal. If that won't work try another key.
Alternator Feedback through speakers
What kind of feed back ? Does it get louder with RPM . Ignition system can also cause this . But just to be sure have the alternator check for ac voltage ripple .
Ripple voltage is when the DC voltage varies between (for example)12.5 Volts and 13.5 Volts, and does so rapidly. Technically, an alternator produces "alternating current", (hence the name, 'Alternator') and that AC voltage is converted to DC by running the current through a bank of "diodes".
Alternator Diode Check and AC Ripple Check

Check to make sure your battery terminals are tight. You will be amazed how many problems start there. You can also remove both connectors and and clean the terminals very well. Get some dielectric grease from the auto parts store to help prevent oxidation which will also cause problems.

Where is the fuel pump fuse located on a 2001 gmc
The underhood fuse panel is marked and the fuel pump relay is there as well and they fail as the pumps fail tooand they need to be replaced if the pump does any way. The ground wire for the pump is sometomes overlooked when putting the tank back in as its on the top of the frame rail on the drivers side nearthe tank. It can be dirty too. Lesten for the pump running by having someone cycle the key with your ear against the tank it should come on and shut off a few seconds later. if its working. some can be put in wight the wires backwards and they run backwards but make no presure. Chaek for fuel pressure at the fuel rail. and many pump failures are because the filer is stopped up or theres somthing other than gas in the tank water) ( sugar ) some new pumps don't make enought pressure. Below 50 Lbs. it won't start. Adding gas or even carb spray to the air inlet may get it stasrted. The air in the system may get out then and it'll be OK. Sometimes the battery will be too low to turn the pump on but the engine will still crank
Location of backup light wires in cab?
Most likely not in the cab. Check the harness on the neutral start switch on the transmission. That is what turns on the lights when you shift into reverse.
