Question type: General
My 2010 f150 truck won't start in the mornings but
will start after the weathers warms up. I have
replaced the Battery to no success. I also took my
truck to Auto Zone they tested the alternator and
starter and it tested good.

Is the engine turning over when trying to start?
Cold weather tends to make things contract, even a little. Contraction, coupled with work contact points can cause voltage to the ECM contact problems. Try this. Place a small electric heater inside the vehicle on the floor, set to the lowest possible temperature, just enough to warm up the inside of the vehicle several degrees. If it starts, suspect the ignition switch, not the ignition cylinder. You can do the same with an electric hair dryer aimed at the bottom side of the column. It's probably a lot safer, especially if you forget you have the heater on inside the car.
Have the car checked for codes when running, even if no idiot lights are illuminated on the dash. "No start" or "hard starting" conditions can be caused by problems with the EVAP system. The EVAP system in 2010 Ford F-150 usually occur when individuals fill the tank with gas then keep clicking the fuel handled to squeeze the last possible drop of fuel into the tank. This causes raw gas to be forced into the canister, causing various problems within the system. When the filler nozzle clicks off the first time, it's full.
anybody can replace a battery and think they are doing the right thing. Watch what you buy.. I had a mechanic ( who just replaced my gas pump in my front tank- only necessary in states that only one tank needs to pass smog) tell me that he would put an interstate or dekka battery in a Ford. BUT, are you looking at your CCA when buying the battery?? check to see you have an 850 cca 12v battery. When things get warmer, take it out and go 650 or 750 cca and you'll be fine. Secondly, when the system is cold, it takes a while for fuel pressure to build up. So, let it do it's job and work up the pressure and turn it over. Have you noticed on common daily driving in town when you turn off the motor over and over and it starts right up?? It's because the system has already established pressure in the fuel system. you wouldn't just jump out of bed and expect to run a marathon, would you??same theory here, good luck
