If you are getting no signal when testing the running light pin on your 2009 Ford F-250, with a tester like part # PTW2991, then it very well could be a fuse or relay. When I looked up the online owner's manual for your F-250 it looks like you want to check the relays in the #42 and #55 positions in your Power Distribution Box.
Let me know if this doesn't fix your issue and I can help you troubleshoot further. I have linked some helpful articles on wiring to this answer page for you to check out as well.
