Hi, I'm Bogi, one of the auto experts on RepairPal's Car Genius team! Thanks for including all those details, it's clear you've already done some solid troubleshooting! On your 2011 Ford F150 with the 3.7L V6, a starter that continues to run after releasing the key is telling us that the starter circuit is staying energized when it shouldn't be. Since you've already ruled out the fuse and swapped the starter relay without any change, there are only a few other options. One strong possibility is a faulty ignition switch, which on this generation F150 is a known issue. The ignition switch can wear out and fail to properly cut the signal to the starter circuit when the key is released back to the run position. A stuck or faulty starter solenoid is another possibility, as the solenoid can sometimes stick in the engaged position and keep the starter running independently of the relay. It's also worth looking at the wiring between the ignition switch and the starter relay circuit, as a short or damaged wire could be keeping the circuit powered longer than it should be. Electrical diagnosis on starting circuits really benefits from having the right wiring diagrams and diagnostic tools so I’d recommend having a qualified shop check it out.
