Im sure you guys have heard this question a million times. Why is my car not letting me fill up the gas tank all the way without the pump shutting off? It stops every 7/10 of a gallon and then repeat. I have researched it some. I just replaced the fuel filter and that wasnt the issue. Idk if the fuel neck is clogged.....or somthing about a evap solenoid. I am throwing an evap code. This problem is a pain in the a$$. 30 minutes at the gas station every fillup haha. Can somone please help. I have a 2006 LS.

Do you happen to have a diagnostic scanner tool or have you run into Auto Zone to let them check your codes?
If you have a chiton manual, you can look up the code once you find out the code number and see what it is and what to do about it.

Canister evap solenoid. DTC P0449 Evaporative Emission Control System Vent Valve/Solenoid Circuit Malfunction
DTC P0449
Circuit Description
A battery voltage is supplied to the evaporative emission (EVAP) canister vent solenoid valve. The control module grounds the EVAP canister vent solenoid valve control circuit to close the valve by means of an internal switch called a driver. The scan tool displays the commanded state of the EVAP canister vent solenoid valve as ON or OFF. The control module monitors the status of the driver. If the control module detects an incorrect voltage for the commanded state of the driver, this DTC sets.

Takes about 5 minutes to change. About $35 for a new one if you don't shop around.

^ agreed. Your charcoal canister is loaded with gas fumes, which is causing your gas filler to do that. The purge solenoid doesn't contain enough voltage to charge the coil, releasing the gas fumes back into the intake, which replacing it should help. Also, AutoZone's scan tool is just a generic scanner, cheapo. If you want to see what its supposed to read, get one that has access to PIDs to read the voltage on each sensor/actuator. Most generic scanners with PIDs will be for this particular DTC, EGR & EVAP Emissions Control. Should read above .1v-5v max for reference (5v=signal voltage at max load, .1v=lowest reading and solenoid closed).

The one I purchased was a "Dorman 911-036" did the trick.

Will autozone return these parts if they dont work lol. I got a parts dealer i can get this stuff for cost. But i would get it from autozone to see if that did the trick

First remove yours and check it with a 12V if it works everytime and doesn't stick it's not your problem. Remove it before you need to fill your car with gas. If it doesn't kick the pump you know it's your problem. Just disconnect, turn counterclockwise and pull out. That simple, easier than changing the fuel filter I'll tell you that much.

So your saying remove it, go fill up my car, and if the gas pump doesnt kick off, then that is the part I need to replace???? Sorry you are very helpful, but I'm pretty close to retarded when it comes to the mechanics of a car . Now if you need a paintjob, thats a different story.

Exactly, you won't do any harm for a few hours, it's going to set a code but you already have a code.

THAT WAS IT!!!! Dude yall are life savers man. 2 years ive been dealing with this bullshit! And everyone around town wanted a average of $100 to just look at it! Thank you everyone for saving the day!:tha nks
