My Jimmy Won't Take Gas!

So, I can only get $2 of gas into my Jimmy at any one time. It isn't a blockage, I don't think, since i've gotten $8 in once, and $20 once.
Is it possible that it isn't venting well? It is -20 celsius here (about -5 or -10 in the US?), but it was doing it at -5. So I'm not sure if the cold is the problem.
What do you think?
 
Dumb question but did you try a different station?

I used to have problems with just one station in town. All the pumps at that station didn't work well with my truck.
 
It could be a vapor lock , but that usually happens in hot weather
:hmmm: I'd try another station too :dnaughty
 
If the nozzle is bent or missing the spring, it could be touching the inside of the gas tube and shutting off thinking that the car is full. Try pulling the nozzle out a bit. (Or go to another station. ;) )
 
You could try using a gas can to see if you have the same problem. If it backs up then it's a venting problem.
If it works at least you can get fuel in your tank so that you don't run out.

I had a similar problem in a car I had and I used to have to rock the car or jump on the bumper to get it to take fuel. It was some type of air pocket in the tank.

I have that issue with our Envoy, but only at the Exxon station next to the house. I think it has to do with the vapor recovery system. Sometimes it's fine and other times it takes forever because of the constant stops.

I hadn't tried jumping on it, but it does back up. The time I took $20, like Scott, it took forever
 
Do you know anyone at a GM dealer store?
It sounds like this is a not uncommon problem and the dealer mechanics might have a TSB covering it.
Like others, I have had the problem with a specific hose nozzle at a station, but it sounds like you have tried several stations which should have ruled that possibility out.
New truck time? :)
 
One thing that I have done when this problem has presented itself to me is to pull the nozzel back out of the necklike an inch at a time until the flow becomes steady.

You may have already done that. It is merely a suggestion.
 
Yeah, so I brought the car into the shop to warm up today, but when I took it to the gas station (a sixth one), it still didn't work. CLick, click, click -- all the way to $6 bucks.
I'll have to see a mechanic, this is dumb.
 
This might sound stupid but try this when you stick the nozzel in the tank turn it upside down in other words handle to the sky then start pumping I had a blazer that had a problem like yours and this is what I did to gas it up.
 
So we took the charcoal filter off, and there seems to be a fume blockage of some kind. We were able to fill the tank and wait till warm weather on Tuesday and see if anything changes, but we think we need to drop the tank.
 
heres a question,,was it running when u tried to fill it? the jimmys do have an on board vapor recovery sys, if its running the valve wont allow vapors to escape therefore the fuel backs up in the fuel neck.

No, it wasn't running, but if there is a malfunction in that system, that could explain it.
 
ok .. I consulted a master mechanic... first why it happened ...these vehicles can not be topped off when filling..when it stops pumping that's it...if you do gas will go into the air line and clog the line, thus no venting will happen and no gas will be allowed into the tank ... only other cause is a crushed air line..then replacing the line is needed...

oh yeah the cure...Brenton..remove the charcoal filter and the gas cap..blow compressed air through the line where the filter was...replace the filter and then go fill up :D
 
Hey Steve, that's awesome.
I did that, but didn't know it would fix it. So while I had the air hose off, I filled up. I'll try filling again and see if it is fixed.

no problem..just make sure you blow some air through the line to make sure any liquids are out;)
