Fueling While Running - Diesel Forum

jss304 · 11-10-2007, 02:16 AM

I know it's kind of a dumb question, but with all the electronics on this beast I was wondering if fueling while the engine is running causes the check engine light to come on. I know some vehicles that don't have their fuel caps on properly will throw a code, so I wasn't sure if the same applies to these trucks. Yeah, yeah I know that it's a "safety risk" but it's getting colder here and I'd sure like to keep the heat going when it gets really cold.

I always fuel mine while its running. Haven't had a Check Engine light yet.

The only issue you might run into is that the gauge may take awhile to come up to "FULL" (it is called Anti-Slosh mode and may take up to 55 mins for the needle to rise). I experienced this once when I first purchased my truck (thought my gauge wasn't working), then as I drove down the road for about 30 mins, the gauge slowly started to come up. I checked at work and found that this is normal. From then on I filled the truck up with key in the off position so the gauge will respond instantly when I start the truck up.

Did it a few times on my 01. Fuel gauge would read low until the next key off/on sequence. One time the truck went into limp mode so I pulled over, turned the truck off, restarted, and truck ran fine. Haven't tried it on the new 08.

read youre manual. The dist to empty and other stuff in the computer won't read right unless youn shut it off to fill it

I believe it is a state law to turn cars off when refueling. I have seem numerous signs posted at the pumps that state that. Dont let a smokie see you doing that when they make their run in the store for the daily donuts and coffee.

This applies more to gasoline burners than diesels. Having said that, though, there are several states that have enacted legislation to limit idling for pollution reasons.
