This may seem obvious and something you've tried. Have you "pulled up" the gas dispenser nozzle and slow the flow down? Mine is a royal PITA and shuts off early if I don't do this. My daughters Mercury mariner is a bear to get gas in for the similar reason.

Yep. Once it hits almost exactly half a tank, it shuts off and then i HAVE to pull up on the nozzle to get any more fuel into it.

There is more to the evap/purge system than the canisters. Have you checked the purge valves, that is what is failing to let the air out when the fuel goes in and shutting off the pump due to back pressure.

And please remember- the car was not delivered with this "failure to fuel" defect. Pulling up on the fuel nozzle will help, for a while. When the valves fail completely, you will be spending an hour trying to fill your tank and may only get half a tank too.

Trust me dude, I realize this is not an inherent problem. The only thing that I can do is invest all of my time, money and resources into fixing the problem. Beyond that, there's nothing more I can do. Unfortunately, this is my daily driver right now and the only vehicle I have on this side of the continent, so pulling up on the fuel nozzle is a necessary fact of life right now.

NOW - When you say 'purge valves,' are you referring to the purge valve system under the hood on the driver side firewall? That's the only part of this system I haven't checked or replaced yet. If you go back through this thread, you can follow the previous steps that I've taken.

As always, I appreciate all of the feedback and suggestions provided by fellow members. Please don't ever doubt my sincerity on this.

David, did you ever figure this one out or anyone else on here? I am at the same point, replaced everything except under the hood. Still can only fill half way then painfull to fill rest of the way. Any help is much appreciated!

What happens when you pull the nozzle up roughly half way and slow down the flow slightly?

Mortimer:

Funny you revive this thread now! I actually just decided to start trying to tackle this problem again recently. This is to say: No, I haven't yet figured it out! I've replaced both charcoal canisters and the purge solenoid and used compressed air to blow out the lines. I've also pulled the fuel tank all the way out of the car and examined it for possible implosion (it's good).

Contrary to what others have said, continuing to feather the trigger on the fuel nozzle and sneak just a little more gasoline into the tank (after the half-way point) has not caused the issue to become worse. I have been daily driving the car every summer for the past 3 years this way (and who knows how long it was being driven like this before it came into my possession).

The only time I've ever been able to get a full tank of fuel into the car with no issues is when I disconnected the evap system ahead of the charcoal canisters. The car smelled like a rolling petroleum refinery, but it filled all the way up with no issues. This indicates to me that the issue is still located somewhere in that area, rather than under the hood. Obviously this was not a permanent solution, however, as I would have been sick from the fumes, so I quickly reconnected everything.

In response to some questions about changing the position/technique of filling: In the last 3 years, I've held the nozzle at every angle and tried every trigger speed short of doing a hand stand on the trunk lid while vigorously squeezing the trigger. Nothing has made any noticeable difference.

So, where am I at now? Just yesterday, I ordered another purge solenoid (LNC1525AC). The first replacement one I installed was used from a junkyard in Texas, so I can't be sure it's 100% operative. This officially means that I'm so lost at trying to figure this out that I've begun replacing parts twice. I've gone through the TSB for this issue so many times that it feels pointless to continue referencing it. It also doesn't address the possibility of an imploded fuel tank.

Anyway, that's where I'm at. I'll report back when I try this new purge solenoid. If you have any more questions or comments, feel free to pass them along. Hoping that we can both finally get this sorted!

Best,

David

I can fill the tank if I do this. Only works if filling extremely slow. 20 minutes to get other half of tank full. Pisses the wife off LOL. Just read Dave's post after yours, Thanks Dave for the reply. Pretty much my situation is identical and feel your pain. Parts I got were used but pulled from working environment. Will see if your new part works and will do the same if is the fix. Tried multiple different gas stations and angles as well. All roughly same result.
