Hello, my 2005 5.4 has 62000 miles on it the truck runs fine with no driving issues at all. When starting in the morning fires right up I drive to work about 2 miles park it and it sits for about 3- 4 hrs and when I try to start it it just cranks. Tried turning the key off and on the only thing that really helps is if I hold the pedal to the floor and then it idles high for a couple seconds. Then it runs and drives perfect. It always starts but will just crank when key is only turned. If I go right home and shut off and then try to start it the truck fires right up with just the key no pedal if. I let it sit for a while seems to happen again but doesn't need to crank as long. In the morning the next day fires up no problem. Again runs and drives perfect always. Took it to the dealer after it threw a misfire code during one of the hard starts told them to check for leaky injector they said everything was fine. Any ideas it seems to get worse longer crank to start when the wether gets warmer but it does happen all year round. Oh one more thing sometimes when I try to start then stop and try again the truck fire up and the radio is dead. The fuse is not blown but if I take the radio fuse out and put it back in the radio works fine again even after changing the fuse it still does this occasionally when starting. Sorry about the long post but I'm stumped. Thank you
