My 2008 f-150 will start fine at times and other times have to turn off and on 4 or 5 times to start
May want to check to see if there is any codes the PCM is throwing...Auto Zone or O'reily's Auto should be able to help you with that. IF your key has a chip in it try another key see if that helps. Other then that, "there could be other problems such as fuel delivery." Does the engine turn over when you try and start it and it just don't start?? Turn the key on and listen to hear if the fuel pump primes in the tank for second.
