been havin problems with our yukon starting. so we had it narrowed down to the ignition switch, brought it to the dealer and had it replaced. it ran great for a little over a month. then it started losing power when we were driving. i would press the gas pedal then nothing. the car died on the side of the road, we sat for a few minutes then crawled home. next day started fine then it started acting up again. i was pretty sure it was the mass air sensor so i bought one from the junk yard put it in the car ran great. turned the car off after my test drive now its doing the same thing it did before the ignition switch was replaced. there is a clicking noise in dash when i turn the key but it wont turnover the ignition lights dont turn on either. starter will spin if jumped but the car will not turn over. any suggestions im at a loss

Sounds like the fuel pump is gone my friend. Had the same issue with my 04 Denali XL and it was losing power on the highway. Replaced it myself and it now runs like a champ. Also if you see that your gas gauge and miles to empty are changing from how they used to be...its definitely the fuel pump. Mine did the same and once I changed it..it still wasn't showing the right miles to empty but on the second fill up it went back to normal. A month later and she's still running like a champ.

but would the fuel pump cause the car to not ever turn over. the only sound i hear is a faint click in the dash

I am from GM Customer Service. I would recommend at least taking it to the dealership and have the vehicle diagnosed. That way you’re not guessing what the problem is, and you can figure out how to proceed from there. Thank you.

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 150 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.
