I think it's interesting that a brand new vehicle has run full blast A/C just to get cold when my 6 year old 100K vehicle that I haven't touched the A/C system since the compressopr replacement 2 or 3 years ago and 70K miles ago will blow air cold enough that even on the hottest days and going down the road it gets cold enough that even on low setting it cools the vehicle... btw the vehicle is a 2001 V6 ex-cab S-10. You would think that a brand new vehicle with all the technology we have would be able to have an A/C system that works even on the hottest of days. My wifes 04 Impala also doesn't get extremely cold. At least not as cold as my S-10. Her car only has 19K miles on it. Haven't had any problems with it. Just that the A?C doesn't get cold

Does anyone know the location of the Oil Pressure Sending unit on the 5 cyl engine. Is it perhaps on the left side behind the exhaust manifold.

You could have a bad gauge, or a problem in the wiring harness between the fuel sender in the fuel tank and the gauge. Bad grounding in the circuit will cause erroneous readings too.

13 MPG sounds dismal on this truck. Either something is wrong or you are flooring this thing at every opportunity. For comparison, my full size '06 Silverado Z71 crew cab (4WD) gets 15-16 MPG in town, more on the highway when driven CONSERVATIVELY. That's with 5.3 liter V8 and 3.73 gears, with A/C on all the time (I live in Florida).
i would recommend trying higher octane fuel. The computer will advance engine timing more with higher octane before the knock sensor registers pinging, for better mileage. Try 89 for a while, then 93. See if the mileage improves. Avoid jackrabbit starts.
I run my Z71 Silverado on 89 octane brand name gas, such as Mobil or BP. Avoid cheap no brand name gas stations. who knows what additives they use. Too much enthanol in the fuel will lower your gas mileage.

Never Mind gents. Upon a more detailed look I found it. The location is right above the oil filter itself.
#197 of 199 Problems with starting your canyon??
Aug 30, 2006 (6:11 am)
I have a 2005 canyon that has decided not to start. I had to have it towed because we could not even jump it. The dealership is taking days to charge the battery. I do have a pretty extensive stereo system in it. Would it be taking the all the juice from the battery?? I have had the stereo for a year now and no problems before. Or could it be something else? I do not want to pay out of my pocket if this is a problem with these trucks.

Hey I have the same problem I have a 06 Crew cab 4x4. My gas gauge first started saying i had half tank then it would go to empty then re start and would say empty . Then next day just stayed on empty had half tank in it .Took it in they replaced the fuel pump module and the sensor , they called me and said it was still saying empty. so they are looking into it some more . Let me know if you found out what it was . Thanks

As you may have noticed, we are reorganizing the Forums to allow better focus and easier searching when you have a particular problem or comment about any given vehicle. Many of the large generic discussions (like this one) will be closed to new posts, and we ask that you continue in the more focused discussions that you can find at the Group page for the vehicle, linked below. This discussion will not be deleted, so you can still search for information in it.
We recognize this is going to take some getting used to (for the hosts too!), so please bear with us. If you have any questions, you can always email the host of any discussion - the link is at the top of each page to the host who oversees that discussion.
If you don't see a discussion in the group appropriate to your question or comment, start a new one, or send me an email, and I'll point you in the right direction!
