I have a 2005 Jaguar W Type 3.0 which gives me problems when I try to pump gas. The pump nozzle won't stay on - keeps clicking off and won't let the gas flow steadily into the tank. Never ever had this problem with another car. Can't figure if it's something I'm doing wrong or not. Has anyone had this problem?

 

Correction, it's an X type. Not W type (typo)

 

Take q look at the opening in front of the filler (after you open the filler door). Notice that there is a holder for your gas cap on the side facing the front, so the cap doesn't just hang there.


Now, look towards the back of the car. Notice that there is a rectangular indentation at 9 o'clock in the opening.


Hold the nozzle so that the base is in the notch!


That's all there is to it!


Upside: no gas will drip from the nozzle when you are done filling. Downside: you have to hold the nozzle there, although the stops will work.

 

 

I have now an engine light on and following codes came up: P0456 + P1111


Any idea if these are related to me not being able to pump gas?

 

P0456 is (ostensibly) an Evaporative System Leak.


What is probably is, is a loose gas cap.


P1111 is a general code that tells you that all tests have run successfully.


Remove and re-secure the gas cap, the code sure clear by itself in short order.

 

I had with same situation with one of my Mazda vehicles. It happened on occasion then would disapear.

 

May want to replace your charcoal canister between the fuel tank and the engine. When they get old they clog up and cause these type of faults.

 

I've had the issue with my Jag a couple times as well. It's the angle the filler is at. For one when setting the stream of fuel set it to the lowest setting on the pump handle. Yes you may have to stand there an extra minute but hey at least you get a full tank. Also you may find pulling the handle out of the hole a couple inches will allow it to work also.

 

That 'sideways nozzle' thing is by design...there is a method to the madness! Hardly anybody uses the system that way, but try it, you'll be surprised.

Three things are affected by the sideways fill; first, the purge flap is designed to keep the gas fumes in the tank, and allow air OUT while you are filling; holding the port open or holding the filler neck out allows air to mix with the gasoline; this can actually cause a big bubble on the off-side of the fuel tank. That bubble can cause the CCV to stick open.

That will keep you from getting a full tank, and depending on where it is, can actually throw the P0456, when you open the cap, you effectively 'burp' the tank.

The third is that you won't get that last drop falling on your finish after you pump.

Denso designed the system, it is used on some Cadillacs and some Mopar diesel pick-ups, too.

If you just smash the nozzle in there like we do on most cars, eventually the hole will hog out and it will work, but that is not actually how it was designed.

Most manufacturers (Jaguar included) don't use it as designed, heck, there have been TSBs from different marques on how to 'correct' it !

 

I should probably mention that there is a 'vent' on the charcoal canister that will allow the tank to 'breathe' with the filler neck in the 'usual' position...which is why only some of the cars have this problem.

You can "fix" it by replacing the canister, but you can still slam the gas in faster using the sideways trick.

 

Hey Crew, I know this is old, but I wanted to give a +1. I did this just the other day. I haven't changed the charcoal canister yet but reading and doing this significantly helped me fill the tank. No where near like it should be but at least tolerable. Try it.

Wow, I was just thinking about this. I have had a new charcoal canister for 2 years now, but it seems the problem eventually goes away on its own…..that, and I am not sure how hard it is to replace. Some posts here say it’s just a matter of patience and using a long screw driver to get to the part, and others say you need to drop the tank a little bit.

 

I had mine replaced and you need to completely drop the tank.

Dr Dome on this forum has done his something like 3-4 times on his car(s) and said indeed you need to drop the tank.

 

Thanks. Well I guess that’s getting put on the back burner for me

 

You don't have to drop the tank on the Estate: Pry the canister solenoid off it's Christmas trees, open the top and pull out the rubber diaphragm. Put it back together and if the solenoid is stuck open it'll work, if it's stuck shut replace the unit.
