#1 of 43 Hard to start car after gas fill up.
Jul 13, 2006 (8:18 am)
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?

We experienced the same problem with our 2003 Santa Fe this morning. Until now we have not had any problems. When we gassed up the car it would not start and even after it did the transmission would not shift out of park for a few minutes. This happened to us twice today. Our car has 112,000 miles. Sounds like a very similar problem. What did you find out and has it been fixed? If you have and don't mind what did the dealer charge if you took it back to him?

This happened to us twice today.
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.

I have not had the problem fixed yet. A mechanic suspects a clogged gas tank filter. Problem is, it looks like the entire gas tank has to be removed to get to it, and it is not a sure bet that that fixes it.

I have a 2002 Santa Fe (6 cyl) with only about 35,000 miles on it and this identical problem just started for me about six months ago. Maybe it is a fuel filter. I have to admit I do run the fuel level down too far (same money used to keep it a lot fuller!) Anyway, does anybody else notice a correlation between the problem and letting the tank get low? I'm not sure if the two are connected, and I'm still not sure why if it is the fuel filter, why does it clear up? I know that many cars these days have pressurized fuel tanks. I wonder if the problem may have something to do with taking the cap off and depressurizing the tank... I say this because I can shut the car off a few miles later, wait a few minutes and it starts right back up. The only difference I can see is that I didn't remove the fuel cap. Any ideas on this?

I do not think it is a pressure problem. If I only put $5 of gas in to a fairly empty tank, the car starts as normal. If I fill up past 1/2 tank, the problem happens. It seems like air or vapor must somehow be trapped in to the fuel line.

Sounds like the emissions evaporation system could be clogged? Charchol cannister might be soaked or otherwise bad? I am reaching here, but it might be worth a shot.
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.

Not a bad idea. Let's see... if it were the emissions evaporation system, why do we only get the problem at gas stations when restarting? ALL my other restarts are perfectly normal, including first thing in the morning, when the engine is cold (like after work) and after the engine has warmed fully (like stopping at a convenience store after driving for awhile, etc.)
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!
