Hooking up a scan tool to see if the PCM/ECM - engine computer will communicate should be first step . A non talking PCM would cause this problem . Who erased the codes ? Is the battery good ? Do headlamps work ? Inside lights ? Won't start how ? When you turn the key to the start position does anything happen ? When you turn the key on does the check engine light lite ?

2003 gmc yukon denali through a mass air flow sensor code changed still having problems with it stuttering to start and while driving on freeway or at stop light when taking off


Trouble codes? If none, then check O2 sensor outputs and replace as needed. Could be a leaking intake manifold gasket if you get "lean banks" codes. This happens in cold winters, but fixes itself in Spring.

Want to know if i can put a differential from a 2007 tahoe on mi 2003 denali xl mine is lock


Look in the glove box and look at the GM PRO Code sticker. Look for the codes GU1=axle ratio 2.41 GU2=ratio 2.73 ect up to GU6=ratio 3.42 or it may be GV which is the rear axle ratio codes. As long as the codes on the Tahoe matched the Denali your good to go. Good luck and keep me posted, If you'll like me to let you know your rear axle ratio and if it's a locking or not just ask, be glad to help
