Roll Damn Tide!
The last few months, every time I fill up, my truck wont start on the first try, it hesitates and I'll wait a sec, then try it again, and cranks on the first try. Anyone else have this problem??
Possibly developing a venting problem. Do you have problems filling too, or just a rough start. The first link seems like it describes your symptom. The second is more about overflowing.
If if there is help in those threads and report back.
