have a 2010 f-150 with 5.4 liter engine. after it sets overnight or allday it is hard to start. it will crank over and try to start. after doing it about three times it will start and run fine. any help would be great.

let it sit over night or how ever long it needs to get it to duplicate the symptom. cycle the key on and off(do not start) 4 to 5 times. this should kick on and off your fuel pump and preasurize your fuel lines. if this works and your vehicle starts you probably have a fuel pump going out.
