#37 of 46 2005 Colorado Check Engine Light evap leak small P0442
Dec 20, 2011 (8:03 am)
I have a 2005 Colorado with 68K miles, the check engine light recently came on, it shows two codes, both P0442. Mine is an I5 engine 4WD, extended cab. I understand this indicates a leak in the evap ssytem, which the sensor checks by trying to hold vacuum. I replace the fuel cap to no avail. Does any one know of a way to defeat this sytem to make the Check engine light go off, like plug the line between the sensor and the tank?
I bought this truck new, it has been a troublesome vehicle, tire wear that seems to unfixable, water leaks, multiple elctrical problems. I should get 150k miles or 10 years with zero problems, very disappointed in this truck.

I understand your frustration, and can appreciate the fact that you are seeking to resolve these concerns on your own. If we could look and see if there are any open recalls or special coverages on your vehicle, we would be happy to do so if you were to email us the last 8 digits of your VIN.
I realize that working with a dealership is not an option at times, whether due to technical expertise or other factors. If you do decide to work with a dealership in the future, though, I just wanted to let you know that we would like to make sure that things go well. Just let us know through an email (preferably, if you could include your name and contact info, last 8 digits of your VIN, the name of your dealership and appointment information) and we'd be sure to follow up on that.

#39 of 46 Intermittent Acceleration Hesitation
Jan 13, 2012 (10:06 pm)
I have 2004 Colorado Z71 Crew Cab With I5 engine and I'm experencing intermittent hesitation on acceleration, expecially when I first drive off after vehicle has been sitting for a while and cold. I have already experenced the Carbon Buildup in the Throttle body and I just cleaned that and I am still experencing the hesitation problem as if it is not getting fuel. After a few seconds it will continue acceleration. Anyone experenced this problem. P.S. Also the engine light comes on for a couple of days and then resets.
#40 of 46 06 Colorado with startin issue....
Nov 07, 2012 (6:30 am)
I have an 06 Chevy Colorado, bought it used with 50,000 miles. My husband and I have put about 10,000 miles on it and had no problems until a few months ago. We thought it was the fuses at first because the first time it wouldn't crank one of the fuses had come loose, it happened once more with the fuses so we replaced some of them. Have had issues where I couldn't get it to crank so my husband would drive home from work to only have it start up the first time he tries!! The probem has progressively gotten worse over the last few weeks, where it would happen every once in a while to where it was an everyday, nonstop thing. The last two weeks it has taken longer and longer to get the truck to start up with trying to start it in the ten minute intervals. This past week the time frame went to 15 to 30 minutes of trying to an hour and half sometimes two hours of trying till it would finally start. Three days ago my huband spent an hour and a half trying to get it to start doing the 10 min. of wait time, and it would start and then sputter out and die a few times before it finaly started up and ran just fine. Yesterday we tried it and after two hours of trying couldn't get it to start. So we had it towed to the dealership and it actually did the same thing there, it kept sputtering out and dying on them too! Mechanics are saying it is the fuel pump, that it isn't holding pressure, hooked it up to the machine and showed my husband the gauges and it really isn't! Has anyone else had the problem? I have scoured the forums and seen a lot of Colorados with starting issues but none that end like mine. Just wondering if it really is the fuel pump or should I still be worried about the Passlock system, we thought it was that at first too!

Oh the mechanics told us that the reason the fuel pump has gone bad is becaus its only driven around the city. I am a stay at home so only do around town driving. I had a Chrysler Mini Van for three years and thats all the driving it got exept for one trip to Florida, never had to replace anything on it!! Their reasonin just doesn't make any sense unless its a design flaw in the system!!

#43 of 46 Re: fuel filter [dick28540]
Dec 09, 2012 (7:07 am)
i have a 04 Colorado, and the gas filter was very easy to change.
JUST BE SHURE, YOU BLEED THE HIGH PRESSURE OFF GAS LINE. BEFORE YOU UNHOOK ANYTHING. unplug the fuel pump FUSE, start the truck,let it DIE,
(or run out of gas). then and only then UNHOOK fuel lines from filter, which IS OUTSIDE,of gas tank. my 04 cost me $15.00 to buy, and my time.
WARNING....... DON`T PUT THE FILTER ON BACKWARDS. WATCH THE ARROW,
MARKED ON THE FILTER. THE ARROW WILL BE POINTING (AWAY FROM THE TANK.) Now how simple can that be? and oh yes, PUT THE FUSE BACK IN.

ok you will love this problem,
seems evap system is faulty, but i saw the gas beening put into my truck,
and as the pump shut off automatic, i saw a gush of GAS behind the gas filler neck.
So i took off the rear splash shield, to see the FILLER tube, i cked it all, and could NOT find anything loose, or cracked, missing. So i shall watch the next fill up. with the shield OFF, IT DID GUSH BEHIND THE GAS FILLER DOOR.

I have experienced a similar problem with my 04 Colorado Z71 Crew Cab 3.5 I in the past couple of months. I have encountered a problem of not starting eventhough the engine turns over normally. After sitting for a few minutes and retrying, it started. The last time it took longer for it to start. I came on here to see if I could get some answers as to what was causing the problem. It is as though the ignition was turned off or fuel shut off. I was also concerned that it might be something to do with the security. Did replacing the fuel filter take care of your problem? If so, how expensive was it?
