Looks like you're not getting much input. My 2004 doesn't have a problem starting after a fill, but it is a total pain to fuel it up! Sort of like spoon feeding the beast! It's a Flex-Fuel vehicle and when I had it on the hoist, I was amazed to see that the fill pipe is not very much larger than the fuel dispenser fill nozzle! I'm looking for any ideas about improving this situation. Hope you were able to find out what's going on. Have you read codes, if any? Sounds like an EVAP situation to me.
