It can be either relay or fuse issue. Get both of them checked.

SOURCE: The other day I went

Did you touch the acceleration pedal, if you did it could be fuel build up. Does this happen all the time when you start the truck. If so it could be valve seal that are leaking.

SOURCE: Electrical Problem - dead battery

Sounds to me like you may need a new rectifier put in the alternator,a shorted diode in the alternator could be powering up things that should go dead with the key in the off position.To prove this,instead of pulling the fuse,take the plug out of the alternator and if all is well,you have your answer.

SOURCE: What does reduced engine power light mean

this model has what they call fly by wire.. no accelerator cable. If the computer detects a problem in the thottle system it will not allow the engine to accelerate and will show reduced power and possibly set a check engine light. The dealer usually wants to replace the throttle assembly which is very expensive and usually un nessesary.
I have had a lot of succes with just cleaning the throttle plates real good.

When I turn my key to start I get nothing. No lights, radio, interior lights, nothing

sounds like you need a battery check first, if ok possibly bad connections on battery terminals, possibly duff starter motor or solenoid, failing all that a dead short somewhere maybe need an auto electrician to check it out.

Access code for 2003 envoy radio

costs money, it will never be free.
only how much and trouble are the variables.
is this SAT code? or is the radio bricked, from car battery dead.
if radio is dead, in all ways that is bricked.
aka: theft deterrent mode, asking for password.

Jumped a car, now i do not have power to windows door locks, radio a/c heater, dash board lights, radio or alarm, what can i do to fix

try disconnecting your battery ... completely... touch the battery cables together while they are both DISCONNECTED, and this should reset and clear your computer. Reconnect everything and try. If this doesn't work, you probably destroyed your computer by jumping the other car off.
