Hyundai Santa Fe Fuel and Fuel System Questions
I have a 2002, 6 cylinder Santa Fe with 120,000 miles. It generally runs great. Thee only problem I have is after I fill the car with gas, it is difficult to get the car started, and it runs rough for the next minute or so. Has anyone heard of or had this problem? What is the fix?

I am assuming you didn't fill up twice today. If that is the case, on the second try (without the fillup) were you restarting after recently having turned the engine off? I'm wondering if it could be a problem with your injectors.
tidester, host
Also it's possible you have a bad gas cap that is not properly venting. Are you putting it on tightly enough to click it at least three times after fill up.
The ONLY time it happens (at least for me) is gas station restarts and the only thing that's different about them is that I've removed the gas cap. I'm in New Jersey and when we go through inspection, they specifically vacuum test your gas cap (I didn't even know they did this until I failed last year for a bad gas cap on another car). I'm guessing that certain cars are designed to have "sealed" (non-venting caps) and vice versa. I'm not sure which we have, though I would think that the point of an emissions evaporative system would be to NOT let the gas vapors escape out the cap, but rather to force them to vent into a charcoal canister and then get sucked back into the intake air stream somehow later (like my old GMs did). I can't quite figure out why a vented cap would be a good thing, but there are a lot of them out there, so there must be a good reason for them. In any event, I still say it's coincidental that the problem only happens when the gas cap is disturbed- everything else (including the charcoal canister, injectors, fuel filter, etc.) doesn't change during my "non-gas-station" start-ups.
Since it's cheap enough to test (I would hope), I'll try another gas cap and let you know if it does anything.
Keep me posted on your progress and thanks for your input!
I too have not brought it in for service yet. I realize this thread hasn't been updated in several months, but I was hoping somebody has something new to add.
All I can add is two things to do in the meantime:
1. When you start the car after gassing up, give it a lot of gas. The car will rev up and after a few seconds, throw it into drive. If you have enough room to go for a while without stopping, it should be ok. I've been filling up late at night when the stations aren't crowded to do this.
2. Leave the car running while you gas up. Obviously this is something you're not supposd to do, but it can work. The first time I did it, the car did sputter out and die while gassing up. But I tried it again recently and the car stayed running and I was able to drive off without a problem.
Unfortunately, my Santa Fe has over 60,000 so the repair was 250 dollars. The part is only 36 dollars - the rest labor.
I urge everyone to go get their valve replaced now while their car is under warranty.
when restarting. My mechanic turned up clueless after witnessing it for himself. I did notice that after pulling over and trying to duplicate the problem by removing the gas cap and shutting the car off, you are able to here the gas gurgling which I never noticed before in this car or my other car. An other suggestions other than a gas cap which I will try this weekend?

Fuel pressure regulator?
Other ideas?
Thanks in advance,

Maybe that will help.
The reason of the issue was the Accelerator Position Sensor malfunction (code P2125).
I paid $121.70 for the accelerator sensor and $156.66 for the labor. Total was (w/ tax) $297.87. I had it replaced at D'Arcy in Joliet, IL.
I hope it helps.
Thanks
