My 2006 Envoy Denali stops running suddenly and then refuses to start

Asked by Aug 30, 2014 at 08:33 AM about the 2006 GMC Envoy Denali

Question type: Maintenance & Repair

The engine quit while driving on the highway.  Both check engine lights came on.  After 45 minutes while waiting for a tow the car started.  Dealer replaced the ignitions switch (shorted) and computer reprogrammed for "driveability".  The throttle body had been replaced about 6 months before.  After repairs exact same problem occurred.  Second tow to the dealer and resultant "loose connector on main outlet from fuse box".  Picked car up and got 10 miles before same problem occurred.  Any ideas.

Don't Sell it. Trade it in. Once you get into running take it to a dealer that didn't work on it.

This is a serious problem with this truck the dealers are guessing and guessing wrong people are replacing ignition switches, fuses boxes computers, and after 10 mins of driving same problem, will I fix the issue by powering up the fuses that was not getting power when truck would not crank and all tap of difference codes would appear and disappear when starts, in my truck those fuse are # 31 55 23 26 54 56 30 and I power up this fuses by taking power from a open J case fuses ran a wire from j case fuse to fuses # 31 and it power up all the fuses above then I had to power up the fuel pump relay by using a 30amp fuse and using power source between fuse # 27 and 29 it comes on when you turn the key open and off when you turn off and then I removed the pcm fuses, fuses # 10 in my truck and my truck has never ran better does cut off.
