Has anyone else ever had this problem: I have a '99 elantra that constantly shuts off the gas pump regardless of whether I have a half a tank or a completely empty tank. I have been to multiple gas stations and have moved the pump around a million times to different angles etc. the tank spits out gas and it takes me forever to get a full tank when the pump automatically shuts off every 2 seconds. The hyundai dealer blew the lines out but it didn't help. Any advice??

Only time I've ever had a problem is with those pumps in Cali that you have to put in then push down to activate them. They're touchy and shut off sometimes, but I can usually get them to work ok. I can't think that it would be a problem with the car itself, unless your filler tube is clogged or something (the tube that goes from the tank to the outer gas cap)

try to put it in only half way is what i have to do

I have the same problem with my 2000 elantra. My car was taking gas fine until last summer. Now no matter where I take it or how I position the pump, it automatically kicks off the pump. It takes a loooong time to fill the entire tank since it only takes a little bit at a time. Even holding the pump half way out doesn't really help. Any suggestions???

I'm having the EXACT same problem with my 2000 elantra. First, my "check engine" light comes on. As soon as I unscrew the gas cap, I get this suctioning, "whooshing" sound as if the gas tank was trying to breath. Then it will take gas in about 20 cent increments. I've taken it to the dealer 7 times in the last 3 months. They've "cleaned it out", replaced a part, and now, tomorrow, I'm taking it back yet again. It's good for about 1-2 weeks, then same problem!

could have a clogged canister vent or a clogged air filter for the canister or you could have a clogged canister, the vapour has to go somewhere when you fill your tank

Ok looks like I have joined the crowd. My son was given a 2000 elantra and it too does not take gas. Has anyon found the real solution? The filler tube looks clear. This vapor canister I think is located behind the gas tank near the bumper, if so is it a comon part to find or filter to replace?

My car was having the same issue.

Every time at the pump I would have to keep the nozzle locked at the 2nd notch instead of full flow in order to keep it from tripping. I talked to a mech and had them replace the vapor outflow valve (I think was the name of it) and it worked like a charm.

Car takes gas real easy now :)
