post icon fuel fill trouble Hyundai sonata Sign In

I'm having trouble with a late model hyundai sonata ( I believe 01 or 02) When filling the fuel tank from near empty, the pump will occasionally stop after pumping a gallon or two, as if the tank was already full. The MIL occasionally comes on, but i haven't had an opportunity to check the code. I don't even know if the DTC is related. Just wondering if anyone has experienced a similar problem. I know the possible causes, but any information regarding the most likely causes would be greatly appreciated. Thanks in advance.

Still get the code read but doubt it's related to this exactly??

Just curious - from where it shuts off early will it finish normally?

BTW but shouldn't be the up front issue - It's best to NOT let fuel get too low as the fuel actually helps keep fuel pumps running cooler and better for them,

The tank will not fill up normally after the pump clicks off, it continues to click off on repeated attempts, and sliding the nozzle partially out does not remedy the situation either. The car belongs to a friend of mine, so i haven't actually witnessed whether the MIL turns on at the same as the problem occurs (JIC that question pops up). And thank you for pointing out that a full tank is good for the pump; I know this, but i didn't think to advise her.

Thoughts and a maybe on this:

Routinely running low probably is hard on the evaporative emission system and the code may show that. The vapors need to be dealt with by the car itself and there are more of them vs liquid fuel when low - duh. There may be a connection there that will lead to the solution??

Re: fuel fill trouble Hyundai sonata Sign In

Thank you for your input Mr. Greenleaf. It is greatly appreciated. I'm sure if that's the cause an EVAP code is going to be hiding somewhere in the history, at least i hope so. (I live in the NE part of the country with no garage at home, so i don't like to spend too much time outside searching blindly for problems this time of year) I'm going to pull the code before I take any further action. I'll keep my fingers crossed that it points me to the solution. Thanks again
