Question about 2002 Hyundai Accent

1 Answer

Hyundai Accent 2003 - gas pump clicks off when tank isn't full.

Gas pump continually clicks off when filling tank even though tank isn't full. It shuts off every few seconds therefore it takes about 10 minutes to fill the tank.

    From Hyundai Service Website (which is awesome)
    All 1999 and later Hyundai vehicles incorporate a new emission control system known as On-Board Refueling Vapor Recovery (ORVR). A general schematic of the system is provided below.
    Some owners may experience difficulty filling their vehicle with gasoline and a premature shut off condition as a result of the gas pump nozzles installed at their gas stations.
    If the refueling difficulty continues, verify that the 1/2" vapor path from the fill vent valve on the gas tank to the air filter on the charcoal canister (see schematic below) is completely
    free and clear. To perform the procedure below, make sure the fuel tank is below 1/4 tank full.
    To quickly determine the general location of a possible vapor path restriction:
    Disconnect the hose connected to the canister side of the liquid-vapor separator (see schematic below).
    Take the vehicle to a known "good" or major brand gas station.
    If the vehicle readily accepts fuel, the restriction is located between the liquid vapor separator and the air filter.
    If the vehicle does not easily accept fuel, the restriction is located between the liquid vapor separator and the fuel tank.
    On-Board Refueling Vapor Recovery (ORVR) Schematic
    The following components are contained in the ORVR system:
    Vapor hoses
    Liquid-Vapor Separator(s)
    Fuel Fill Vent Valve
    Fuel Cut Valve (anti-spitback)
    Canister Close Valve
    Air Filter
    Charcoal Canister
    After the restriction has been isolated to either half of the system, inspect each component to make sure it is free and clear of any restrictions. Verify that no
    back pressure can be felt anywhere between the fill vent valve and the air filter at the canister.
    1999 Accents have two (2) liquid vapor separators: one located on top of the fuel tank, the other located alongside the filler neck.
    When checking the liquid vapor separator, blow through one end of the pipe using lung power. NO
    back pressure should be felt.
    Verify that the Fill Vent Valve is open by carefully removing the valve and confirming that the white plastic shut-off plunger moves freely inside its cage.
    If the fuel cut valve plunger is stuck closed, a hard-to-fill condition may result. Verify that the plunger moves up and down freely allowing fuel to enter the tank, but does not allow fuel to travel up the neck (under pressure). The plunger should be "up" (closed) in its free state.
    When working with the Fill Vent Valve and associated plumbing, be sure to replace the hoses into the proper hose clips to prevent fuel from getting trapped / puddled in the vapor hose. Return fuel from the liquid-vapor separator must have a clear path to drain back to the tank.
    Four Way Valve
    The Four Way Valve provides an additional vapor path to the canister during refueling.
    NOTE 1999 Sonatas have a Four Way Valve located between the liquid vapor separator and fuel tank.
    Proper operation of the valve is as follows:
    Air flows freely in either direction through the 1/2" ports.
    Air flows freely in either direction through the 1/4" ports.
    Air flows from 1/2" port to the 1/4" port when blowing into one of the 1/2" ports while plugging the other 1/2" port.
    Air does not flow from 1/4" port to the 1/2" port when blowing into one of the 1/4" ports while plugging the other 1/4" port.

Why does the gas pump cut off every 1/2 to 1 gallon on my 2003 Hyundai Accent, at slow pump even when the tank is nearly empty. It doesn't matter what station I go to.

Failure in the Evap System

Check for Evap Codes & diagnose that system

Most likely a failed evap vent solenoid

Google : OBD PO446 thru PO449 & read up

Gas tank hard to fill up

First thought is fill tube vent hose. Just remember, if you check it, that it is full of gas vapors, which explode by design. Stay alive and unscorched.

Can't get gas into my 2002 Hyundai Accent.

The reason the gas station pump shuts off is when the fuel reaches the tip of the gas nozzle, so when you are filling your car and the gas nozzle (gas stations pipe) keeps shutting off it means that the pipe that runs to the gas tank is not open completely, what happens is when you pump the gas in the car the supply pipe from the gas tank opening to the tank fills up quickly and this causes the gas station pipe nozzle to shut off, have some body take down the gas tank and have a look at the gas tank opening and also gas supply pipe that runs from the gas filler opening ( on the car body) to the gas tank. Have a look at it and please don't forget to rate the answer if it was helpful, thanks!

Car will not start after refilling the gas tank on a 2003 Hyundai

sounds like you have a bad vent on your gas tank
next time try leaving your gas cap off after you fill and try and start then
if this works just drill a vent hole in the gas cap
or change the tank vent filter

Problem trying to fill the gas tank. The pump shuts off continually even though the tank is no where full.

It's not the car, it's the vapor recovery system on the pump nozzle. Report it.

2004 hyundai accent. trouble filling gas tank

I have a 2005 Hyundai Accent, It is not possible to fill the tank if you are letting the petrol pump run at full speed.Trying to fill up quickly it will only build up pressure and cut off. Next time you fill up just pull the petrol pump handle half way, it will take longer to fill but you wont get the blow back. Modern petrol pumps are getting quicker all the time.Hope this helps you.

Try moving the handle in a different position, or don't put the nozzel all the way in. The vent tube could be clogged.
