   Might want to get some gas additives to remove water and condensation from fuel lines. Fuel filter could be frozen up. If not the problem you could always try cleaning the plugs. Could of got sooted up from burning frozen fuel.

   Since this truck is an F150, it is probably a gas engine, 5.4L v8. Deisels were primarily in F250 and F350.
   The problem depends on what you mean by won’t start. Does the engine crank over but the engine won’t fire or does the engine not crank at all.
   If the truck is parked out side and the engine cranks but doesn’t fire, it is most likely the fuel lines are froze. The best thing for this is some Heet fuel additive. It’s not a miracle cure and takes some time to mix with the fuel. Using a space heater to blow warm air under the vehicle will help thaw the lines. This can also be tested at the fuel test port on the fuel rail, it’s a shrader valve that looks like a tire valve stem and has a black plastic cap. Remove the cap and depress the valve to relief pressure. This truck has a fuel pressure rating of 54-59 psi, if you have a gauge to test it.
   Use caution when doing this as it is gasoline and it is or should be under pressure. If light pressure is visable the problem is in the fuel system, ie. frozen fuel line, bad fuel pump, or a bad fuel pump relay. I would say a dirty fuel filter, but this truck’s fuel filter is in the tank as part of the fuel pump module assembly.
   If the vehicle won’t crank, the problem could be the starter soleniod wire on the back on the starter. It’s the small single wire that has a spade type/slide on terminal. This is common for corrosion on a lot of ford vehicles. Removing the connector and reinstalling it a couple times will help the connection. If this does correct your problem, I would recommend some dielectric grease be installed on that terminal to avoid further problems. Most auto parts store carry this product in small sample type packets for a buck.
   Hope this helps fix your problem, but a little more information about the problem would be very helpful in diagnosing the problem. Good luck. Christopher

   the alternator has nothing to do with starting system,that’s part of the charging system,
   Check for a spark at the plug wire,if you have spark, then it is a fuel problem,pore
   some fuel additive into the gas tank, might be fuel line freeze up !
