03 won't start

I hav an 03 f150 SC 5.4, 120,000 miles 2wd. Lastnite I shut it off & it wouldn't restart, I checked all fuses and none were blown. I Checked under tha hood with a test light & one fuse would light up, it wasn't blown but while I had it out there was sound that started kinda a viberating sound. I put tha fuse bak in & it lif up tha test light. Truck started & ran fine. Same thing next 2 times I shut it off. It's not showin check engine light. Thanks for any help

Sounds like a bad relay. Find which one of the relays is making the sound and replace.
