My 03 denali has hesitation to start and causes my radio to reset?

Sure, you’ll need an aftermarket stereo to take advantage of this. Is it worth that to you? If so it’s only $200 or so for a super nice head unit capable of this ad of today, that includes a back up camera too.

I'll try to help, everytime something gets replaced on these yukons, that circuit needs to be RESET ! Is there a reset button, on your steering wheel, to reset a variety of functions ? , check owners manual, or call your dealer for better advise

a lot of times factory defaults on the radios is something like 0000 or 1111 or something like that. If not, you can pull the deck out and reset it.

This can be fuel pump related or just fuel filter related, spark plugs and injectors.
When engine is cold vaporization of gasoline is minimum. When fuel vapor is less than required and the fuel mixture is not ideal, ignition happens harder than it does under ideal running conditions of engine. When fuel pups is sweak, or filter is limiting, or fuel injectors are not injecting gasoline with improper pattern inside engine, or just becasue of corroded spark plugs, cold engine faces difficulties during first ignition.

PS: sometimes car starts and stalls.it fails to start once more. this can be a sign of broken crank position sensor. FYI.

There is no such thing as a "cold start valve" but there is an IAC motor that adjusts the idle speed, and they can fail/stick and not turn on the check enging light. There are a couple of things that can cause what you are describing so I wouldn't just start throwing parts at it. You really need to have a shop with a scan tool have a look at it.

How to fix the steering wheel options on my steering wheel, for instance the volume for radio, onstar, etc? I have a '03 gmc Yukon denali xl

03 denalis do not have one, Gm discontinued them in 03,

the mode door actuator is under the drivers side foot area on the left side of the heater box. it has two 7/16 screws and one connector

check your manuals guide book on reprogramming the radio and where would you find the fuse for the radio first check the fuse then reprogram if this information has been helpful please let us know good kuck

generally it would just need to be reset... unhook the battery for about ten minutes and hook it back up. make sure you have the unlock code for the radio FIRST and you know how to enter it.
