Hey Everyone -

I bought a 2013 F-150 4x4 with 130k miles. The truck has no problem starting except right after I fill-up. I have to slightly press the accelerator during a long startup to get it to fire. I've been able to get it started every time, but I have filled up about 10 times and the issue has happened after each fill up. Any incite would be appreciated.

 

Possibly evap purge valve under hood is stuck. Was a common issue. Also check fuse 27 in the engine bat fuse box while you're there - make sure it's not discolored
