#13 of 46 Check engine, Fuel cap
May 06, 2009 (11:16 am)
I have a 04 crew cab colorado I5 86,000. This one is hard to explain, the check engine lite comes on only after the dashboard fuel cap lite comes on, this only happens sometimes. It seems to be more when it gets warmer temps outside. I live in Indiana so the temp. fluciates so much its hard to tell. Im on my third gas cap, i bought the caps at different places thinking one was better than the other. i tried the disconect the battery thing for 10-15 min that shut it off for a day or too. this has been going on for a while now. Can anyone tell me why or how.

Since changing caps isn't doing the job, you probably need to have your tank vent checked.

#15 of 46 screwy defective fuel gauge
Oct 06, 2009 (1:50 pm)
I bought a pre-owned '05 Canyon 2 months ago and I had noticed the engine light was on. I brought it to the shop and they plugged the car into that computer module that reads all the problems with the car. The problem was with the fuel gauge and the sensor in the fuel tank. When the truck was sitting still, the pin on the fuel gauge would slowly go up and down. Never giving a true fuel reading.
I was driving a hill one day and the truck started to cough and buck. It then stalled. The fuel gauge read a 1/4 of a tank of gas.
To make a long story short...they put in a new fuel sensor inside the tank. All new parts the mechanic said. $275 worth. I was driving up another hill and what do you know, the truck coughs, bucks and stalls. No gas at 1/4 of a tank again. No 'low fuel' warning light....nothing. From a full tank I waited for it to get to 1/2 and filled it up. At 1/2 of a tank it took 15 gallons. The size of the tank is 19.8 gallons.
The mechanic doesn't know what to do now.
This happen to anyone? Any suggestions what the problem is?

yes, mine is doing this as well ('05 canyon w/">91K miles). I bought a new solenoid ($105 w/shipping) from gmpartsdirect.com. Just installed it and haven't confirmed it works yet. Here's the issue: the ventilation of the tanks is the problem. A month ago, got the gas cap code (engine light). Replaced the gas cap, no change. The tank never pressurizes and gas always sprays out when the pump shuts off. The vent is apparently open when driving, and closed when pumping (thus no release of pressure as the tank fills up). I'm hoping it's a bad solenoid on the vapor canister, but I'm shooting in the dark a bit. There's another part (purge valve) that I may have to try and it's $18 before shipping. Hope this helps. Appears this will occur on every canyon/colorado when they hit the 100K mark.

I have a 2005 Chevy Colorado 4wd 5-cyl. (91,000). If my truck sits for awhile while it is running my check engine light will come, after I drive it for awhile the light will reset itself and go off. Well now, the light has come on, and the last three times that I have tried to get gas, the pump will shut off after about 70 cents. I have to stop for a minute and then start again. It takes forever to put as in it. When I unscrew the gas cap I hear a pshhhhh. like air is coming out, can someone help me here.

#22 of 46 tank vent solenoid
Jun 02, 2010 (4:10 pm)
I don't drive my Canyon 4x4 too much in the summer, it's primarily a winter use vehicle. However, a couple of weeks ago, I needed to get a few bags of fertilizer and some mulch for the gardens, so out came the truck. A couple of miles down the road, on goes the "fuel cap" warning message on the dash. The truck's gas cap hadn't been touched in quite a while, but when I get to the garden center, I check it anyway...it's tight. I get the light again, while on the way home.
I install a new cap, as it's not too expensive, and thoroughly clean the inside of the filler neck. To test things out, I drive the truck to work the next day, message re-appears on the dash. Get home from work, throw the scan tool on, get "major air leak in vent line" error code, as well as "intermittant lean mis-fire" error code.
I clean the MAF and throttle body, again clean the filler neck of the tank, and clear the codes. Test drive truck, "gas cap" error message again. Take truck to dealer, they replace the tank vent solenoid. Yes, I have a few months of my GMPP warranty left, so they "cover" the bill, but it's $100 deductable. Yeah, I know that dealer labor isn't cheap, but I know the part, in reality, is about $25-30, and I gave them the error code from the computer, so that minimized their diagnostic time. I also heard that this isn't all that rare of a problem. But, it still cost me $100 out of pocket.
Yes, I know the truck is 5.5 years old, but it has under 30,000 miles on it...SHEESH! I sure hope that this isn't the beginning of a trend.....
