#16 of 46 Re: Gas tank overflows when filling [mikeof48]
Nov 06, 2009 (9:48 am)
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 (3:10 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.....

I was having the same problem. We have an 04.I took the bed off.It was located on the frame in front of the spare tire.We took the canister off & hooked it up to a 12 volt charger to see if it was opening &closing.Staying closed all the time.There's a spring on the inside.We took it out & put it on the other side to hold the vent open all the time.Fixed the problem & didn't cost a penny.Hope this helps.
