True. I never leave mine running or leave the keys in a car when I go inside the building. My regular gas station had a car stolen that way a couple years ago. And it'* a "good" neighborhood.

PCM detects a large leak in the EVAP system, then generates a DTC. It is highly recommended to turn the engine off while re-fueling though.

Myth, not a myth. There are simply too many accidents and problems cause by mistakes where any of us need to test a big bang theory.

I've filled up a number of OBDII cars while running (the '98 and '00 Bonnevilles included), and never have thrown an evap code.

The fuel system is pressurized. When a leak condition is encountered the code is set. The check is not run everytime or every start (which is why it takes a while for the code to clear itself after you fix it, usually the gas cap not tight). If I recall its about every 30 starts or so.

As for filling the car while running, I know many ppl who do it, I choose not too for simplr common sense reasons. Gas does not ignite easily (ever try throwing a cigarette into a pool of gas?) however gas vapor is extremely flammable and pumping gas into the tank lets fumes push out of the tank while you displace with fuel (mmmm that gasoline smell). Doesn't make much sense to take a chance on igniting those fumes however rare the chance may be.

I don't care how cold it is outside, I shut my car off while fueling up. IT'* not like it'* going to get that cold inside the car in the time it takes to gas up, and it won't take long for it to heat back up either.


one time though I had a gas station attendant wig out on me because after I was done fueling I ducked back into my car to check a text message, the attendant came out yelling at me because I was on the cell phone while people were fueling up and I was going to blow up the whole station .

She got very irate with me when I told her it was more likely I would start a fire by starting my car up then by checking a text message on my phone INSIDE my car. Should have seen the look on her face when I was driving away while she was still going on about what a danger I am and if she ever saw my doing that while at her station she would call the police

The reason I do it is mainly because of the temps. Living in North Dakota about 25 miles south of the Canadian border, a lot of times I start the pump and get back into the car and wait until it'* done. Also due to my location, a stolen car would make regional news, so it doesn't happen too often. I guess I'll just have to adjust my fillup procedure on the bonneville, but there is no way I'm turning off my '97 F250 Powerstroke while I'm filling up.

In the winter I leave my car running while gassing it up. I always have. Is it smart? No. But who said I'm a super genious anyway lol. I know the dangers, and I know the odds of it happening. But it'* so fargin cold outside and I'm a woosy, I get back in and stay warm while it fills up.

Seems the general consensus here is that fueling with the vehicle running isn't a really great idea.

Regardless of whether individually we understand the risks, there is potential. The person fueling next to you may not want that golden opportunity to spend months on end in a burn unit.
