Had the same concern. Had to take mine to the dealership and have them replace the system. Be careful when you change between the drives. Vehicle MUST be in park, of course started, and you can change the drive. WAIT until the light completely stops blinking before placing into gear or trying to change to another setting. When you change the setting, a gear arm raises or lowers, and resets. Listen and you can hear it. Often when the vehicle has sat for a while, or if the battery has been disconnected, you will hear it resetting. If this does not work, you have to take it into the shop to have the gear sensor repalced.

SOURCE: replace starter on 2002 GMC Envoy SLT

check to see if the starter itself is getting a signal to crank. youll need to use a test light and have someone else try to start the vehicle, while you probe the wire to the starter to see if it is getting power. if not, check the starter fuse to make sure its not blown, as well as the starter relay to make sure that is good too (very common on gm's for bad relays) if the fuse and relay are good, but your not getting signal, it is an ignition switch problem.

The plastic intake should have this sequence molded into it somewhere, and even the corresponding cylinder numbers in front of their respective holes. Have fun, and thanks for posting on Fixya.com

If I remember correctly if you look at the back side of the fuse cover, it should tell you what the fuses are. Also in the owners manual in the index, under fuses, it should give you a diagram of the fuse location for the acc. outlets. Good luck. The fuse should be a 20 or 25A fuse.

Sounds like you may have disconnected the battery. Does the rough idle only happen when the defroster or A/C is on? If so clean your throttle body with throttle body cleaner with the battery disconnected. When finished, drive it for 5 or so miles with the defroster / AC off to let the computer relearn the settings. This will solve your problem.
