cannot fill fuel tank

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.

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.

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.

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

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.

Well Mortimer, I wish I had better news for you today but I don't
Just replaced the purge valve with a brand new one (LNC1525AC) and no luck. Same problem. Once it gets between 1/4 and 1/2 tank it starts shutting off. Wish I knew where to go from here - Those carbon canisters are bloody expensive to buy new, and I probably won't lean towards doing that this summer... If anyone else has any thoughts, feel free to chime in

For some odd reason I can now fill that tank or at least 90% full for the last 2 times. I didn't do anything so is random good luck. Only thing I can say is I live in Florida and over the past month is into the 90's each day now. Have been filling after driving a while so is good and hot. Maybe the extra heat is helping evaporate gas from the carbon canisters? No other real insight.
Anyone on here have ideas of what I could look at if heat is helping the situation? Guessing issue will come back after summer is over

Hi all,
Going to resurrect this thread again. Have owned the car for 4.5 years now and have yet to get this issue figured out. There are 2 problems as I've come to realize: One is that the sending unit is bad, the other is that the pump shuts off at almost exactly 1/2 tank every single time I attempt to fill it. Just last night, I ran the car completely out of fuel, then tried to fill it up. When it got to 11.7ish gallons, it stopped and wouldn't go further.
I've replaced the CVV twice now, so it's pretty safe to say that's not the issue. I've had 2 different shops and one Jaguar specialist look at the car, and all believed the issue was the CVV. Anyone who has more/different ideas or suggestions, feel free to chime in.

A bypass for this...
99 XJ This happened to me today..
I cannot put more than a gallon or two in the tank, and even that takes 20 minutes. the fuel gauge seems accurate, but the tank simply will not accept more than a bit of fuel, leaving me always almost-empty. this has been going on for weeks so I've tried every combination already of nozzle, timing, etc.
Thanks in advance for any advice or diagnostic insight.
Also, are there any inexpensive scanners to read codes on this car?

.I read the forum and went back to the gas station ,and left my car running...filled right up...

My 2002 XJR has suffered from the same problem, although it seems to vary a bit. Sometimes it does fine, sometimes I can’t fill more than about 3/4.
I have found a couple of things. For some reason the filling goes best with the tank almost empty. When I try to fill up from about half full, I often experience.
The other thing that seems to work is to keep the nozzle aligned along the car/boot, rather than have it perpendicular. Somehow, it appears that if I try to fill up with the nozzle perpendicular I have this problem more often, or earlier (i.e. not able to fully fill)
But then again, in my case it all seems a bit random. And so far it is annoying, but nothing beyond that (yet). So I havent really started doing anything about it yet.

Kingman,
Thanks for posting this. Leaving my car running while filling up was next on my list of things to try, along with bench-testing the charcoal canisters.
If the car fills right up while running (as in your case) what would this seem to indicate is the fault with the system that prevents it from filling while the car is turned off?

Next time that i fill up,I am going to leave the key in the on position.with the engine NOT running .I will try to fill it normally first but if the CCV is malfunctioning, I will have to get around that inconvenience.. Hopefully all will be normal, but,with a Jag,normal is dubious,at best!!

Hi I am having the same problem i replaced my fuel pumps a few months ago had various problems after that that were electrical replace the electrical
in back by gas tank now the car wont take gas into the tank when you go to fill it up it wont keep the nossle up to pump the gas in Any suggestions also my gas gage is showing full but right after i had the tank replaced i ran out of gas

Team I need some guidance and or help!! Check engine light is on and can not pass emissions test. Had it in the shop and stated the issue was to do with a leak in the rear canister. Not able to find a new replacement part because it is discounted. To add to the issue went to add fuel today and the fuel will not enter the tank. Did anyone come up with the solution?
