I have a 6cyl Optima that recently has begun having trouble starting after fueling? Any ideas?

Is the Check Engine light on? Tester

Do you have the habit of trying to get every penny of gas in the tank when you full up, or do you stop when the pump shuts off. If you force more fuel into the tank…after the pump shuts off…you can saturate the charcoal canister and it can make for hard starts. It’s one thing to “round” the pump u…

It’s impossible to pack a gas tank to the point where it saturates the charcoal canister. The EPA knew there were morons out there that would try to do so. So since OBDII was introduced, the EPA demanded a method be devised to prevent that from happening. So the Onboard Refueling Vapor Recovery s…

Interesting. Do you have a link or something to confirm that the EPA requires an overfill check valve since the switch to OBD2? That’s not something I was aware of. I can find all kinds of information on overfill prevention valves for underground storage tanks but not for cars.

Onboard refueling vapor recovery An Onboard refueling vapor recovery system (ORVR) is a vehicle fuel vapor emission control system that captures volatile organic compounds (VOC, potentially harmful vapors) during refueling.[page needed] There are two types of vehicle emission control syst…

Thanks. I know the EPA requires a vapor recovery system when refueling but you mentioned that “So since OBDII was introduced, the EPA demanded a method be devised to prevent that (fuel from saturating the canister) from happening”. That Wikipedia article doesn’t show that - it just describes a ven…

Vent/Rollover Valve [8] [ dead link ] It provides a method of controlled escape for gasoline vapors during the refueling process. It has a mechanism which closes the vent in the event the vehicle rolls over, to prevent spilling of VOCs or fuel in general. It also acts as a fill limiter. What’s so har…

Easy. Where does that say it prevents fuel from entering the canister? Where does it say the EPA requires this device on all OBD2 vehicles?
