Question about 2002 Hyundai Santa Fe

1 Answer

Putting Gas in my Car has become a drag

Every time I put gas in my tank, the car fails to start on that first initial start. I have to wait maybe 10-15 mins before it'll try to start. I've gotten tune-ups, oil changes, and filter changes. What causing this and how much will it cost to fix?

Sounds like a fuel pump problem, when it won't start check the fuel pressure at the fuel injection fuel supply rail on the engine, there is a valve there to access the system pressure, it looks like a metal tire valve.

2003 Chevrolet Silverado 4.3 V6 with MFI. Engine ran not start.


Well it could be numerous if things but you want suggestions...So here's mine..Your gas tank might be vapor locked...This is caused from over filling your gas tank with gas over the years..Its when the pressure in your gas tank becomes greater than your fuel pump. It wont start until the pressure in your gas tank becomes lower then you fuel pump...Sounds crazy...This got me once...I didn't understand it...A lot of people (including me) Go to the gas station and get that extra 50 cent after the gas nozzle clicks off...over time that extra gas will run down the vapor lines intended to burn fumes....Like when you fill a gas can to cut your grass...If you sake the gas can it builds pressure and bows up. But with time that pressure will go away...Well saying that...Your gas tank needs to vent to....So your car burns not only gas but fumes...If you keep over filling your car with the extra gas it cloggs up your vapor canister intended for fumes or vapors...The gas will will go into that canister and clogg up the charcoal that's inside it. (Breaks it down) then the vapors can't get to your carburetor where it supposed to burns it. So what happens is the pressure in the gas tank becomes greater than your fuel pump and then car won't start..Are you with me? Lol Its crazy..Putting a different gas cap can cause the same thing...Simple test...When you open your gas cap to get gas.. Do you heat air sucking in.. Yes you can hear it....A lot of times loosening the cap let's the pressure out and the car will start right up.....Thus might not be your problem but worth telling at the gas pumps to other people..... Just trying to help

2003 Cadillac CTS-When stopping at a light the car would turn off but was able to restart. Car eventually died and would not restart. Had battery checked then replaced as the battery was bad. Once the new...


Just guessing but trying to help...Your car might be vapor locked..Take off your gas cap... Do you heat KT sucking in air as you take it off...If you do your car will now start...A lot of people at the gas pump will try to get that extra fifty cent in their tank at fill ups..Thats the worst thing you can do. What your doing is putting gas down your gas vapor line...Its meant to burn vapors from your gas tank..When you over fill your gas tank this gas runs down that line into a canister that has charcoal as the filter built inside. Over time your gas will harden the filter to where it becomes clogged..Then as the pressure in your gas tank becomes greater than your fuel pump...Your car will shut off not start back up until the pressure in the tank drops....You can replace this canister... Most are behind your headlights on drivers side..Its that little black box your never did anything..On some vans there underneath...Another thing :is as these canister's go bad your putting all that broke down black charcoal right into your carburetor.. That's those lines thats those lines that are hooked to it at the bottom...So your feeding your car junk...Never over fill your car because in time it will shut off...So just loose the cap and lesson for air sucking in....Try to start it with cap off...More unlikely you have a non stock fuel cap..Either drill tiny hole in the center of cap or replacei it with factory stock...Also some cars have a fuel shut off switch that will shut the gas off in crashes...Sometimes these switches will go bad....they can be reset...Might be in truck under matting....Good luck...Hope all of this helps someone

I ran my car out of gas and put gas in it now it wont start


How much gas did you put in it? It is very possible that when you ran it out, that your fuel filter became clogged with the sediment from the bottom of the tank. Make sure there is atleast 5gal. of fuel in the tank. Turn the the ignition all the way forward and wait 3 seconds, but dont turn the engine over. Do this 5 or 6 times to get the fuel pump priming. Then try starting the car without pumping the gas pedal. If the car still wont start, check that the fuel system has pressure. Maybe something failed in the fuel pump when it went dry. You can have someone listen near or at the fuel tank to see if they can hear the fuel pump kicking on and off while someone turns the key on and off. Hope this helps.

Every time I put gas in my car it takes approx. ten minutes before it will start up. I let my car run while putting gas in it and my car stopped running. But I was able to start it back up 10 minutes later


keeping the vehicle running during a fill up is a definite NO NO! there is the increased risk of a fire(very bad) the possibikity of someone stealing your car(bad) and the increase for the problem you are experianceing( not so bad, fixable and preventable). the reason youre having the trouble is youre essentially flooding the engine with raw gas. while the engine is running it creates vaccuum in the evaporative emission system. in a nutshell, its constantly sucking the fumes out of the gas tank and burning them by running it thru the engine, there is a small valve in the tank thats supposed to be exposed to air in the tank, when you fill the tank with the engine running you are drawing this air out while the fuel is being added and you are more than likely sucking the raw fuel into the charcoal canister and its becoming flooded with fuel instead of vapor. after you wait about 10 min this exess fuel has evaporated enough that just the vapor is being drawn into the engine again and allowing it to start. in short dont keep the car running while filling, dont fill past where the hose shuts off the first time, trying to cram an extra half gallon into the tank, and this should no longer be an issue.

Every time i am putting gas in my car it would shut off or kick back gas. I have tried different pumps even try puttin gth egas in slow or not putting the nozzle in all the way and nothing helps


Sounds like you have something stuck in your gas tank maybe someone put something in your gas tank perhaps you might consider a good flash light and a pen open the cap insert the pen hold tight and put flash light in filler neck flap hole to see what kind of obstacle you have stuck in your filler nozzle neck if your unable to see anything you might consider taking the car to certified technician for service to you clogged gas filler neck.

The car started good and then stalled about a mile down the road. we thought it ran out of gas, after putting gas in, the car still wont start.


make sure it not time to replace the fuel filter you can do this put in some STP gas treatment if the car runs better replace the fuel filter and the sparkplugs also give these websites atry www.alldatadiy.com and www.autozone.com if all fails stop by your local library and get your hands on a Haynes auto repair manual for your car make sure you have a half of tank of gas and add a little more when you put the gas treatment in and drive on a back roard where you can drive around 55-mph wish you the best of luck Michigan Man.

My car doesn't start after putting gas in it


hmmm, is it a diesel or gas powered VW?

if gas, did you use E85 fuel? this will make it very difficult to start and run very poorly once runing. I would suggest a fuel sample be drawn. but first, call the suplying fuel station and ask them if any issues with their fuel. It is becoming more of a trend that teh 10% ethanol is "dropping out" of the fuel. this process is called "phase seperation". phase seperation occurs when water becomes mixed with gasoline that is mixed with ethanol. the enthanol is loosely bonded to the fuel itself, but is much more deireablke to mix with water than gas. so when your service statiojn refills their underground tanks, and the water content in bottom of tank is high, the water mizes with the fuel and pulls the ethanol out of it. the ethanol sits on bottom of storage tank, waiting to be pumped into your car by the submersed pumps in the bottom of tanks....so now that chemistry class is over..call your gas station, ask them if issues with fuel, if co..great! they will tell you what to do next..if not, draw a fuel sample and if it looks like ditch water with water down looking maple syrup like goo in it..that is phase seperation @ its finest.

hope this helps you

your 4 thumbs up is appreciated

Sounds like water in fuel tank. Try putting some gasline antifreeze in, (maybe a couple of bottles) will clear up water and problem if that's it.

Never owned one but maybe your car is Vapor locked...It's when your gas tank pressure becomes greater than your fuel pump..It's caused from years of over filling your gas tank...Your car is designed to burn vapors. But gas goes down the line instead and clogs up your canister meant to filter fumes...Then it builds pressure up in the gas tank. When the pressure in your tank becomes greater than your car...It shuts off and want start back until the pressure has gone down...If this is the problem just loosen your gas cap...it releases the pressure immediately...You usually will hear a suction sound when you open your gas cap....Hope this helps...It could be the problem...maybe not...But something you might not think about or know
