Great video. I can only put in like $8 before gas spills out. The gas station pump nozzle not clicking. But I don't know why my gas tank is refusing to accept more fuel? I've checked all hoses and charcoal canister. Everything is intact. My gas gauge is always showing full. Can a bad gas pump and sending unit be the culprit?Any help would be greatly appreciated. Thank you

Assuming its a similar vehicle, the vent valve is most likely the issue.

Question. can I turn the Vent canister on and off without a scan tool? what are the settings for the multimeter to check the voltage on the wire harness itself? what did you set the multimeter to when you tested the old canister in the car on the seat? I have a 2007 Tahoe 5.3 and I'm trying to diagnose the same code thanks

You need a scanner to command the valve on. If you don’t have access to one then you can try this. Unplug the valve, switch your meter to ohms (Omega symbol). Probe the two pins on the valve itself. If the coil winding is open or high resistance the valve is bad. I would say anything over 40 ohms is probably too much. You won’t be able to check for power at the harness without a scanner. Also all data said something about checking the wiring above the front driveshaft near the transfer case. I guess there is a common rub spot. Hope that helps.

I have a 06 Chevy Express 2500, can you guide me where the gasoline filter is, thank you very much

It may not have a serviceable fuel filter but if it does it will be along the left hand side frame rail.

@@joeburttschell1286 Haven’t used it a ton yet to be honest. I saw it on Pine Hollow Auto Diagnostics and he had great things to say about it. All I can say is it’s done everything I’ve needed it to so far except an oil life reset on a 2012 Land Rover LR4
