Question about 2005 Hyundai Santa Fe

1 Answer

Tempermental starting after fueling

Our Santa Fe runs smoothly with no problems except immediately after a fill-up, usually from about 1/8 tank. Frequently it is hard to start right after filling the tank but after 3-4 tries does start, but runs rough briefly then smooths out after that. It's kinda unnerving!! Any ideas what's up?

    I have the same problem. The 2004 Hyundia Santa fe runs fine and starts fine weather hot or cold. I recently had a complete tune up and fuel system flush. It happens everytime I fill the tank it won't start unless I push the gas pedal to the floor, then went it starts I have to keep constantly pushing on the gas pedal for about a minute to make it keep running. After that it runs fine again.

    I have a 2005 Hyundai Sonata which runs smoothly until I fuel up. I fuel up when it is down to 1/4 tank, then it will crank but not start. When it finally starts, after about 5 tries, it will not continue to run unless I work the gas pedal to keep it running. This takes 2 minutes to accomplish.

What would cause my Hyundai Santa Fe to start hard every time I put fuel in the tank? It doesn't mater if I just put a couple of gallons in or fill it up.

First sign of pump going bad when it is being filled fuel swirls the dirt around in the tank and when you go to start it it is hard. after the pump is running it runs fine til the next time.

The Check Engine Light does not have to come on for someone to find out what is wrong. A shop may have to have the car for a few days so they can run some tests on your fuel and ignition systems. They will most likely have to drive the car/run the engine to duplicate the symptom so they can catch it while it is malfunctioning. Intermittent problems can be very elusive, but they can be diagnosed with a little patience. The level of your fuel gauge most likely has nothing to do with your starting problem.

I have a 2003 Hyundai Santa Fe, lately everytime i fill up it takes a long while to get it started again.Once it's started, it's fine until the next fill up. any suggestions??

Sounds like the purge control valve on your evaporative system is stuck open. In this case, what happens during fill-up is that fuel vapors are forced from the fuel tank into the intake manifold, effectively flooding the engine.
Todays fuel tanks are vented back into the engine. A "Carbon Canister" is supposed to absorb the vapors and then feed them into the engine in a controlled manner. If your canister is saturated or the purge valve stuck open, the fumes can "flood" the engine while refueling. Try holding the throttle wide open when you start after refueling to clear the vapor quickly.

Also next time you go to fill up, don't fill it all the way, maybe half or so, since the evap lines are at the top of the tank this should solve your problem, and give you at least some good information to take to your mechanic

Car won't start after filling up the gas tank.

Just helped a friend fix this exact same issue on his 2004 hyundai santa fe. Replaced the purge control valve - a $39 part, even from the dealer. Had to get our hands dirty, but it took literally one single hour to replace the part. Filled it up immediately afterward and no more starting problems. Part is located directly behind the manifold - top, rear of the engine compartment - just between the engine

I have a 2002 Hyundai Sante Fe. The check engine light has been on for months.No one can seem to find out why. Every time I fill up the gas tank I have a problem restarting the engine - I have to play with...

My educated guess is that the purge control valve is stuck in the open position. This valve is part of the emissions system on your Santa Fe and normally is closed when the engine is turned off. If the valve sticks open, fuel vapor gets pushed into the engine when filling the fuel tank. This creates a fuel mixture that is too rich on the next start up.

Misfire at low revs hyundi 20 crtd 2004 diesel santa fe

Hi, this could be down to the fuel line and injectors being dirty as at low revs their is less pressure forcing the fuel through.
My first thing to try would be to buy a fuel cleaner that you pour into the fuel tank these tend to solve the problem your having.
Make sure you buy the correct one ie petrol or diesel follow instructions on the bottle for amounts to use then run the car for a good run usually takes about 4 hours of driving time to fully clear all fuel lines and filters.
I use this in my car once a month as you can pick up small traces of dirt from filling stations this then clogs up over time.
Hopefully this will solve your problem if not then give me a shout back and ill assist you further

Unable to fill the gas tank when the car is sitting level

These fuel tanks are designed weird, they have a hump in the middle for the driveshaft. Most of the time I have found if the pump clicks off early it is the fuel vent valve, which is located on the rh side, but a fuel cut valve could do the same thing. If the pump clicks off early (sometimes after 1 gal), make sure the canister filter isn't clogged and replaced the vent valve.

2001 hyundai santa fe hard to start engine after filling gas tank

Hello, This is not an uncommon problem and I hope I explain ok. Your fuel pump is located in the gas tank. A pump runs very hot when operating. The fuel in the tank actually helps keep it cool. If you have a weak pump, it is not uncommon for it to fail at the gas pump when refullling. We have towed most fuel pump failures from the gas pumps. This is because the fuel that is in underground storage tanks is very cold. After you shut off vehicle. the temp of the pump climbs a little. When you go to put in new fuel, you are shocking the pump and it quits till it is happy enough to start working again. Again, you are not alone. This is common. Unfortunately, not a " in the driveway job" You need to tell you tech my response and get a quote for new pump. The only other thing that could be happening is " fuel lock" . Next time it happens., leave the cap off and see if it starts ok then. If so, you may have cap or vent problem. I am still leaning towrds the pump. BTW. If I am correct it will get worse not better. At one point it will fail entirely. Be ready for this. Good Luck and Thanks
