Gas Pumping is stopping about 20 x /fillup 2001 XG300

Any ideas why this is happening all of a sudden at various gas
stations, the pump cuts off as if it was filled. This happens about
20 times per fill up. At the same time tonight, I noticed the parking
break and battery warning lights came on and then off and then and
then off maybe in 30 second intervals. Could the gas fill up problem
be electrical? That makes no sense.

 

I've had the fillup problem on my '01 Elantra - exactly twice. I
cannot imagine any possible way that the problem might be electrical,
it's just a coincidence (and not that big of one given Hyundai's
problems had not started to alleviate by 2001).

 

what about the parking break and battery idiot lights going on and it
seems as the the gas pump stopping problem is happening all the time
now.

 

Correlation does not imply causation.

 

Have you been driving through mud recently? I have no idea if this is the
problem you are having but a long time ago I had an econoline van that had
the same gas pumping problem. It turned out that a gas tank vent tube that
I think allows air to escape while the tank fills was clogged up with mud.
After cleaning out the mud in the tube, the fill-ups went fine. And,
"maybe" the same mud is caked around a parking break sensor and causing a
problem there.

This is a long-shot, I know, but I htought I'd throw it out there just in
case. I don't even know if the same type of gas tank vent tubes even still
exist (I have a hunch that they don't).

 

This same problem was aired on "Car Talk" yesterday. The experts said
it sounded like a problem with the emission system - probably a clogged
vent.

Interesting. I like listening to the Car Talk radio show.

 

The car talk people are pretty much right on. Of course, finding the
venting restriction can be a bigger task. If I had to guess on a car
of your age, I'd suspect it's the canister filter.

The battery/brake warning lamps are unrelated. They're alerting you
to an alternator that's not charging.
