#449 of 712 2005 GMC Canyon Problem
Feb 25, 2010 (9:15 am)
Hello, I have a 2005 GMC Canyoun and I have been having some problems with it. For the past few months the engine would turn over but would not fire up, if I left it alone and came back 30 minutes later it would crank right up. Well now it will not crank at all and the dealership is telling me that it is the starter. Would the engine intake valve warranty extension have anything to do with this? Maybe because the engine wouldnt fire up and the starter kept trying to crank the truck it wore it out? Now they are saying 1500 bucks to fix. Any help would be much appreciated.

Sorry to say, I wish you good luck. In previous postings, I mention experiencing the exact problem as you. There are other Forum posts identifying similar Colorado start-up problems, speculating everything from cam shaft actuators to fuel pumps to theft deterrent device fuel cut-offs to injectors -- you name it, the list is large and the problem diagnosis remains undetermined. I had a GM engineer tell me it could be a defective key fob.
Over a period of several weeks during the summer, I experienced irregular no-start issues, although the truck would later start after approximately a 15-20 minute waiting period. The problem ceased for awhile but happened again in December and went away like a recurring phantom. My GM dealer had the truck for 2 weeks and could not repeat the symptom or ID any codes associated with problem.
I subsequently called GM to complain and inquired about the special warranty after reading about it on the Forum. They issued a policy# no questions asked so I took the truck back the dealer. The head and valves were determined to be in need of replacement, as well as a cracked exhaust manifold.
I haven't experienced the no-start gremlin since December, but I now have a mostly rebuilt engine since I took the initiative to contact GM. I suggest you call GM if your truck is under 100K to get the warranty policy and have a dealer check it out ASAP so that you won't take a bigger hit down the road.
No one can say if this issue was the monkey wrench causing my starting issues but I'm keeping my fingers crossed.
#451 of 712 Head replaced, Now MISFIRING worse than ever!
Mar 13, 2010 (6:44 am)
My 05 Colorado with the I5 engine coded "misfire" on me. At about 59k on the warranty. I brought it to the dealer right away were they told me it needed a new head job. This was completly under warranty. OK they do the head and I am a happy customer, they cought a big one before the warranty is up at 60k. Now it is at 61k not even 2 thousand miles after they did the job and it is misfiring worse than ever! It`s running on 3 cyls! The dealer say`s if it was from their work it will be covered, but if not it`s on me! Has anybody like me already had the head replaced and now has a worse skip than ever? I cannot even drive this to the stealer I will have to tow it down on monday! By the way when I first got it back it was running like a bull, I could tell it had so much more compression in it. It was running very strong and I had no real issuses with this truck. I am very mechaniclly inclined and do all my own PM on it. So has anybody alread had their head replaced and now has even more problems with this engine? I am wondering if I should just unload this thing before I get the big one tucked to me!

Same problem with our 05 Colorado. Check Engine light kept coming on - had valves raplaced. Came back on again - finally diagnosed as a cracked manifold. Truck has 110,000 (90% highway). Will start the fight with GM, but don't see them doing anything. Will probably get the same crap about it being over the warranty, but how often do manifold crack ??

Actually, cracked exhaust manifolds on trucks built since the 1970s are pretty common, especially those that are used for towing. Keep in mind that these vehicles have a smog pump which pumps cold air into the manifold when on compression. Typically what happens is that the manifold gets very hot pulling heavy loads up a hill, then cold air hits it on the downhill slope, and crack. At least that's what I was told, and with cast iron, it makes sense. Of course, your truck may not have been used for heavy loads, in which case my post is nonsense.

I am from GM Customer Service. When did the problems first occur with your vehicle? Do you currently have a case with GM? If so, what is the case number? What is the VIN on the vehicle? Thank you,
Mariah GM Customer Service

Yes, clean the throttle body. It is so simple to do, follow the instructions provided by longrunner1. Don't let a repair shop tell you that you need a new throttle body, like mine did. Just remove and clean it. Did it this weekend. Runs like new and no check engine light.

Not sure where to even begin or what post to even put this under. Several months ago my husbands 2005 GMC Canyon's check engine light came on. We took it to our trusted mechanic and he told us that it had a vaccume leak according to the codes. It idles really rough and sometimes dies at stop lights. After a week he still couldn't find the leak. After two weeks the engine started "clunking" when put into drive or reverse. At first we thought we might need to replace the transmission but yesterday it started whistling and squeeling really loudly when the gas was applied but stopped when pressure to the gas was removed. We wondered if it would do this while in park and nothing, until we rocked the vehicle a little, the clanking seemed to be coming from the joint at the drive shaft connect? Any idea's?? We only have two payments left and the vehicle has 70,000 miles on it.
