Just read about your problem. I know this is somewhat late, but my 2008 Denali has failed to start on numerous occasions. I initially thought it was battery, but day after putting in new battery, same think happened. I put old battery back in and returned new battery. Dealer checked it over. Mechanic there told me that the relay/fuse box on firewall where battery/starter cables are connected may need cleaning and tightening. He did this and all was well for a few weeks then occurred again. Went back and he said that GM had informed him that there were issues with the battery cables. I replaced the positive cable (expensive) and no issues for three months. Just recurred this week, have just replaced negative cable. We'll wait and see. I think the next thing will be the fuse (120 amp)/relay on firewall (don't know official name of it). Hope this helps. What is the status with your issues? Have you resolved?

I sent an email to the GM rep on this forum Saturday and am awaiting a reply. Same boat with power cutting out periodically over the past week. Bought it used and almost got a year out of it without problems (other than door locks which were already failed upon purchase). I don't mind paying for the cables but would rather not be raped for the labor on a known issue. I'll update this week when all's said and done so others know what they're in for.
#151 of 156 2007 gmc yukon idle and stall problem
Aug 02, 2013 (10:28 am)
I have a 2007 GMC Yukon, when we start the engine the idle ranges from 500 to 1,000 rpm, bouncing up and down. When we start to drive it, the traction control turns off then it says to check the traction control system and finally the Check engine light turns on. The idle problem continues through all of this. Then the engine has even stalled on occasion. been to the dealer 3 times now. And today is the 4th time! any suggestions???
#152 of 156 Takes several cranks to start....
Aug 04, 2013 (7:38 pm)
Can you please help? (I have an 04 yukon w/5.3 engine) my vehicle has just started doing this...the vehicle takes several cranks and I have to be depress the gas pedal several times before it starts the vehicle does backfire and Boggs out and dies before it starts fully...after it does start the vehicle does run excellent. When I did take the vehicle to a local automotive parts store cause the engine light came on it read that the o2 sensors were bad I replaced ALL 4 and it did nothing to fix the problem. Also the abs light and brake light come on simultaneously every other day
#153 of 156 2008 GMC Yukon Hybrid Stalls Constantly!
Sep 26, 2013 (2:07 pm)
We have only owned our Yukon for 7 months and in the beginning it would stall here and there which we didn't think was a big deal. Now its stalling all the time. We stop try to go and it wont go and jerks you around like crazy. You hit the gas and the RPM go up all the way. We have brought it into a GMC dealership twice.
1st time in dealership: they said it needed a computer update and new spark plug on the engine. So they did that. Mention hybrid battery needed to be replaced and engine wasn't firing. They could not duplicate the stalling issue so they would not fix the battery and told us to bring it back when it happens again.
2nd time dealership: About 4 days later it does it again but this time it wont stop. Jerking the high RPMs and stalling constantly. Take it back to the dealership and they cannot seem to duplicate again. GM tells us we will not authorize any fixes on the car until the car computer spits out an authorized code for the problem.
I am at a loss as to what to do. We paid a lot of money for this piece of junk and all we want is a working car. We are almost up on our warranty and I believe GM is doing their best to make sure we wear it out so we would have to cover the costs.
Read on other forums it is the battery system that is causing the problem, also read GM does their best not to fix it since it is costly! Figures another greedy company that wont cover its own flaws
#155 of 156 car stopped working, replaced fuel pump and...nothing
Nov 18, 2013 (10:33 pm)
Hello - I am hoping you can all help us!
Driving a 400 mile trip our 2001 yukon service engine light popped on. Continued driving it for 60 miles (middle of no where, middle of night), nothing. Started it up fine the next day, 40 miles into drive it began 'chugging', as though it were a fuel filter. Fast forward to today, ran the code, emission code - reset that and didn't come back on. Added fuel additive, seemed great. I go to pull out of the driveway and it died. Wouldn't start - would do the initial turn over but wouldn't fire. Hubby had me turn the key without turning it on and decided it was a fuel pump. Borrowed a vehicle, went and bought one, he replaced it...now...
NOTHING! still won't start adn the fuel gauge won't move...it is though it is still out of gas?! Anyone have any suggestions? Please? Let's start with the easiest/cheapest first cause let me tell you, I can not take any more 'kick you when your down' blows this evening!

Figured it out!! searched and searched and finally pulled the ECM-B fuse...
YEAH!!! fuse was blown!
replaced it, turned key and gas gauge jumped up and instantly could hear the fuel pump working.
CHECK THE ECM-B FUSE!!!
