I like the way the video was done very clear I’m glad you didn’t show your cat and all these other dumb things that other people do you’re a professional thank you
Love those OSHA approved crocs! Seemed like a straight forward fix. Gotta love the one's that don't fight you the whole time. My expedition has been killing me with the EGR system lately.
You can test the purge valve to see if it is stuck open or not. Remove the 10mm bolt holding the purge valve bracket to the engine block. Then move it out for easier access to the hose clips. Remove the rear hose by squeezing the clip on both sides and sliding the hose off. Start your motor and put your finger over the rear hose inlet you just removed. If it is trying to suck your finger into the valve it's stuck open and needs to be replaced. If there's no suction, then it's still good and you can reassemble it. Then you can move on to check for the vent valve being stuck or something else leaking. If your fuel filler tube is badly rusted. It might have air leaks at the any of the connections or through any of the rust deposits. Rule out one thing at a time for leaks. And if you run out of patience get hammered and come back to it the next day 😂
I triggered the EVAP code after I did my undercoating with 4 lbs of pure gum turpentine and 4 lbs of wax. hahahaha. I probably covered up the vent valve - after I cleared the code it didn't come back. I'll take a look again. thanks for the vid - too bad my FailBlazer t-shirt got worn out so fast!! I'm at 292,000.
For anyone wondering how to properly get the coupling closest to the front of the cehicle off there is a push clip on the backside of the coupler. Push in the solenoid and push up on the little plastic piece. It comes right off
You are correct. but I could hardly see the purge valve or get my hand in. So the first thing I did was to take the bracket off and move purge valve out. Then I could see all the couplings and the clips and disconnect them easily. 6:18
Out of the two which is the most likely culprit? I disconnected the battery, didn't help. Gas mileage is 20 which I'm happy with. Code says it's evap system, Envoy runs like a clock 140K miles. So far I'm ignoring it.
It's much easier if you disconnect the bracket first. There's just one 10mm bolt holding the entire assembly to the engine block. Then you can move everything out for a better view of the connectors on the purge valve. And get your hand in easier.

Best vid on this repair. Thank you for posting and placing the cam exactly where we can see the parts. 🙏🏽
Does come with new clips ?
How do you know if the front one is bad or the rear one is bad
How do you test these parts?
Your a lifesaver. Been trying to find where this was located in my Trailblazer.
Great video! Critical info! Thanks so much! I'm about to do the same thing on a Trailblazer I'm working on.

Can it be done from the bottom or just top side?
@@edwardalamo2507 I did it from the top side
I have learned. Thanks for sharing!
Thanks JHunto!
How long did repair take to do? Thanks
Take wheel off helps. You can reach through driver wheel well. Had to for crank sensor there

Thank you so much. I had gotten everything off but this one and couldn’t find any video giving the proper way lol
Wish you had shown where the charcoal canister was
Appreciate it
Thank you for sharing
Awesome brotha thank you
I was told if the vent solenoid was bad, it makes it tough to pump fuel in.
I did this repair a month ago the check engine light was gone for a solid month until today. So I have no idea what the problem could be now 😊
Process of elimination my friend. It could be your fuel pressure sensor that's bad and throwing of a faulty code
How long did repair take? 30 min 60 min? Thanks
Did you have gas smell before fixing ?
Out of the two which is the most likely culprit? I disconnected the battery, didn't help. Gas mileage is 20 which I'm happy with. Code says it's evap system, Envoy runs like a clock 140K miles. So far I'm ignoring it.
Is it necessary to change both Parts as you did? Or can I only change the purge valve?
Yeah, if you are going to shotgun parts, I would replace them one at a time. The purge valve first, and if that didn't fix it, then the other.
Both are part of the same code
Thanks
If your hand is blocking I cannot undo vacuum lines I need to see how it disconnect
them
It's much easier if you disconnect the bracket first. There's just one 10mm bolt holding the entire assembly to the engine block. Then you can move everything out for a better view of the connectors on the purge valve. And get your hand in easier.
Did he say Chevy FailBlazer? 😅😂
Check engine light 07 gmc envoy
Chevy Failblazer 😂
Did I hear Chevy fail blazer ? Lol
En españoñol
Failblazer! lmao
