thanks for the advice but we did take it to the dealer when the ignition switch was replaced and they couldn't find any codes or anything else wrong. they told us the only thing they could think of was the ignition switch. 500.00 and one month later here we are again. we got the car to start this morning with an ignition fuse, but as soon as the car warmed up the acceleration problem started again. we called our dealer everyone is scratching they're heads. so if anyone out there has any clues we would be happy to be enlightened. so far we have replaced the starter relay, the neutral safety switch, the ignition switch and the mass air sensor

Cleaning the IAC worked for me. FYI it was not that dirty so clean it anyway.
#73 of 149 2004 Yukon Starting Issue
Aug 03, 2010 (1:54 pm)
About a week ago my Yukon started to have a starting issue. It will not always start on the first try but always starts on the second. There are a few things that I found while trying to diagnose this problem. It dosen't matter if the engine is hot or cold and it only happens about 50% of the time. If I turn the key to the on position and wait about 3 seconds and then turn it to the start position it starts every time. One other thing I found was if I try and start it on the first try it cranks but does not start and then I release the key to the on position it continues to crank for about 2 to 3 seconds. I then turn it to start and it starts right up. At first I thought it was fuel pressure problem but seeing that it continues to crank after releasing the key from start to on I was thinking it may be an electrical issue with the ignition. If it does start and I release the key to the on position it never continues to crank. It runs fine after it's started. I appreciate any help in where I should look or what to try next. I am leaving on a fishing vacation next week and I will be towing my boat and I would like to try and fix this before I go.

No response from anyone on my issue from this site. I did talk to someone else about this and they told me to try changing the fuel pump relay. They said it was the easiest thing to start with. I am going to get one tonight and try it.

Sorry it took so long to respond and I know how frustrating it is to wait for a solution and nothing. that is why I go to justanswers.com and they have certified GM techs on board to try to solve your issues. The only draw back is that if they fix your issue and you are satisfied with the answer that the Tech has given to you, then you can elect to pay them 18.00 or 24.00 or whatever. But I had to resort to this because I wasn;t getting an answer from anyone and I certainly don't want to go to the dealer and get ripped off again. This is a pretty good site for me and my Yukon issues recently and it works for DIY like me. I hope this helps you it did me.

Next time try Edmunds Answers. Lots of good techs volunteer their time there.
And it's free.
#79 of 149 2001 gmc denali 6.0 rough idle in morning
Aug 11, 2010 (9:15 am)
I have a 2001 gmc denali that runs rough in the morning - usually after it rains or sits (with humid weather). SES light blinks and code indicates all cylinders missing. Problem goes away after running 10-15 minutes (engine heats up). Dealer can't figure it out - recent wires and plugs done. Being told there is no distributor cap / rotor on this engine. Is that true? Any possibility that it is the wire harness? belt tensioners? thanks.
