I work-related with some knowledgeable people here at 1A Auto, therefore after share this through them, they offered me a some tests to check there wasn’t an outside cause.

Before security money on parts, try testing under various scenarios:

Try different gas stationsSlowly eliminate the gas capDon’t location the gas nozzle in all the wayFill up to different amountsDrive various distances prior to filling up (e.g. One mile, ten miles, twenty miles, etc.)Try starting the engine in different temperatures

These components May cause Your vehicle to Not start After gaining Gas

Our experts suggested a part in the fuel and emissions device like the fuel pump, gas cap, fuel line, or another part like the purge valve can be the cause. After browsing online, I found threads ~ above Hyundai-Forums.com and CarGurus.com v others who had this exact issue with mine car and solved the by instead of the vapor canister purge control valve. Due to the fact that most the the human being had success with this replacement, ns took a chance.

Now My auto Starts After getting Gas

After I replaced the purge control valve, she starts up fine.

Since mine valve was stuck open, the purge valve sent out fuel vapor into the engine at start up. Excess fuel vapor gathered in the engine, flooding it before start-up. This explains the have to depress the gas pedal, which opens up the throttle body up and brings in the extra air needed for combustion.

So great luck! This can not work for everyone, but for me and also many rather this addressed a unique problem.
