Fueling problems

Recommended Posts

Any help will be greatly appreciated.

I am down to half a tank of gas and I cannot get fuel into my tank. When I try the fuel will back up out of the filler tube and/or the pump handle will click off due to backpressure. I have tried at three different pumps on two different days with the same results. My local dealer says they have never heard of this and seems to think that it is user error or problem with the pump. I have listened for the electromagnetic click of the inner valve opening when the outer flap is opened and I do hear it. Still I am unable to get gas into the car. As mentioned above my car is an 2004 C2 Cab with 5000 miles on it. I bought it new with 19 miles so the entire history of the car is known to me. One more bit of info, all fuses are OK in the fuse panel.

Please, any advice or ideas will be greatly appreciated.

There was a problem on earlier cars that might be occurring again. Difficulty filling the fuel tank can occur if the flexible fuel hoses in the fuel tank obstruct the inner flap of the fuel filler neck. On earlier cars this was caused by hoses that were not tie-wrapped down and they would work their way up and cause the pressure problem. Since your car is a 2004 your dealer should be able to inspect for this and correct it.

I'm also having this problem with my 1999 C2 Cab. Is there any way to have this fixed other than taking it to the dealer? It literally spits gas back out at me when I try to fill it up.

Any help would be appreciated. Thanks!

I had this problem as well. Sometimes it's a blown fuse (location E6). This fuse controls a vent solenoid that opens when you put the gas nozzle in.

If the fuse has blown and the vent does not open, you get this same symptom, with gas everywhere but in the tank.

Since checking the fuse costs nothing and replacing it costs cents, it's worth a check :)

I have noticed this on my '04 as well, but one thing I did pick up on is that it did not seem to do this at every gas station. - In my scenario it will always just cutoff the fuel flow from the pump and I did not have any proplems with fuel spillage.

I found that if I was experiencing the problem at a particular pump, I would pull the pump nozzle approx. 1/2 way out of the filler and the problem would disappear. ie. Fill the tank up but with the pump nozzle 1/2 way withdrawn from the fuel opening.

Be careful not to squeeze the pump trigger all the way as this could result in fuel being spilt. It seems as if there is some problem only with certain types of pump nozzles and not others. In my case by filling up with the nozzle slightly withdrawn it seems to cure this problem - just remember to squeeze the pump trigger no more than around 3/4 of its travel to prevent fuel spillage.
