Putting fuel in a 2009 ford f150 and it won't crank until i hold gas pedal down

You must have a leaking purge valve that is letting fumes that build up in the fuel tank when refueling the truck. Have the purge valve checked by applying vacuum to purge valve with the engine off to see if it can hold vacuum. If it cannot then replace the purge valve and it will fix the problem.
